摘要： A ring oscillator having an even number of differential amplifier stages is disclosed wherein each stage includes a differential amplifier using two N-channel MOSFETs whose gates serve as the inputs and whose drains serve as the outputs of the stage. The sources of the two MOSFETs are connected together and to a current sink consisting of a cascoded structure of N-channel MOSFETs. The drains of each of the two N-channel MOSFETs serving as the differential amplifier are each connected to a respective current source provided by a P-channel MOSFET. All of the current sinks in the stages are connected as secondary legs of a first current mirror which establishes a current of I in the sinks. All of the current sources are connected as secondary legs of a second current mirror which attempts to establish a current of (1+.varies.)I/2 in each of the sources, where .varies. is a number greater than zero. Since an average current of only I/2 can be drawn from each of the current sources, the voltage drop across each current source is reduced, thereby limiting the range of the average common mode output voltage for each stage of the oscillator.

摘要： A digital data receiver and digital phase-locked loop for providing rapid acquistion and decoding of burst mode data signals, such as Manchester encoded data, without ambiguity. A 180.degree. phase mis-lock detector and phase connector is provided to eliminate any phase-lock ambiguities that may occur. The mis-lock detector utilizes a Manchester data violation detector to determine if the correct phase of sample clock from the digital phase-locked loop is being used for decoding the Manchester data. The digital phase-locked loop utilizes a digital delay line with multiple taps, the appropriate tap, corresponding to a desired phase of a reference clock, is selected as the optimal sample clock. A phase detector determines the difference in phase, measured by the number of taps of the delay line, between the sampling clock phase and the incoming data transitions. The difference is accumulated in an integrator to select the optimal sampling clock phase tap. The phase correction of the sample clock results from switching to a tap on the delay line opposite to the tap being used as the sample clock. Typically, only three data transitions are needed for phase lock.

摘要： An improved CMOS bandgap voltage reference in which a magnified current derived from a thermal voltage reference produces a voltage drop across a resistor. The resistor in turn couples to a single bipolar transistor which is part of the thermal voltage reference. The bandgap voltage is the sum of the voltage across the resistor and the voltage across the bipolar transistor. In addition, the immunity of a bandgap voltage reference to variations in power supply variations is improved by having a differential amplifier sense the voltages at the control current input and the output of a current mirror in the thermal voltage reference portion of the bandgap voltage reference and adjusting the power supply voltage to the thermal voltage reference until the sensed voltages are substantially the same.

摘要： A controlled oscillator is tuned to produce a desired, temperature independent frequency. A first frequency ratio is determined between a first frequency of the output signal generated by the controlled oscillator and a frequency of an output signal from another oscillator. The first frequency is determined based on a sensed temperature. A desired frequency of the output signal of the controlled oscillator is used to determine a desired frequency ratio between the desired frequency and the frequency of the output signal from the other oscillator. The controlled oscillator is tuned and the frequency ratio measured until the tuning has caused the desired frequency ratio to be achieved, thereby causing the controlled oscillator to provide the desired frequency.

摘要： The impedance of the elements of a capacitor array in the transmitter is kept substantially constant over changes in process, temperature, and supply voltage. The impedance is maintained substantially constant by compensating a gate voltage supplied to switches in each element of the capacitor array to adjust for changes in temperature and supply voltage to thereby maintain a substantially constant RC product for each unit element in the capacitor array and thereby improve the quality factor of the capacitor array.

摘要： A one-wire transmission protocol utilizes transition interval coding in which a value of a transmitted symbol is determined by comparing an interval length between the voltage transition associated with the transmitted symbol and a prior voltage transition on the communication link, to a threshold transition interval provided to the receiving device during the transmission sequence that includes the transmitted symbol. If the interval length of the symbol is below the transition interval threshold, the symbol is determined to be a first value and if the interval length of the symbol is above the transition interval threshold, the symbol is determined to be a second value. The transition interval threshold is provided in a start sequence that includes at least two transitions. The threshold transition interval width is based on one or more transition intervals determined during the start sequence.

摘要： An iterative decoding system for intersymbol interference (ISI) channels has a module for extracting bit reliabilities from a partial response (PR) channel, an iterative decoder, and a module for updating the bit reliabilities. A transmitter parses a data sequence into blocks that are encoded to generate a sequence of codewords. By encoding, a correlation among the bits of each codeword output to the PR channel is created. A maximum likelihood sequence detector (MLSD) in the receiver produces estimates of transmitted bits from samples of the output from the PR channel. The MLSD detector has a priori knowledge of typical error events that can occur during transmission through the channel. Along with the bit estimates, at each time instant the MLSD detector generates set of error event likelihoods. These error event likelihoods are then converted into bit reliabilities that, together with estimates for the transmitted bits, are used to recalculate the bit reliabilities using the knowledge of the relation between bits within a codeword. The iterative decoder uses this soft input information (bit reliabilities and bit estimates) for each iteration of decoding to improve i) the estimate of the bit reliabilities, ii) the decisions of what bit has been transmitted, and iii) calculations for the error event likelihoods for the next iteration. These error event likelihoods are then converted into bit reliabilities that, together with estimates for the transmitted bits, are used by the iterative decoder to recalculate the bit reliabilities using the knowledge of correlation among bits within the codeword. The error event likelihoods may be updated using the updated bit reliabilities, and the updated error event likelihoods are then converted to new bit reliabilities for the next iteration. In an iterative manner, increasing those bit reliabilities that tend to show increasing confidence for corresponding decoded bits (i.e., corresponding Viterbi decisions) between iterations, while decreasing those reliabilities that tend to show decreasing confidence for corresponding decoded bits, tends to drive the iterative decoding scheme to fewer iterations while maintaining a predetermined probability of error.
