摘要： In a system having an input signal set with at least two signals having mutually exclusive frequencies f1 and f2 being part of the input signal set, whose amplitude is represented in an input digital representation, the amplitudes of each of the at least two signals are digitally represented. A digital representation of the frequency of each of the signals is derived. A digital representation of the sine function and of the cosine function of the frequency of each of the signals is derived based on the digital representation of the frequency. The digital representations of each of the sine and cosine functions is mixed with the input digital representation to derive digital representations of the sine and cosine functions of each of the signals. The digital representations of the sine and cosine functions of each of the signals are processed to derive a digital representation of the amplitude of each of the signals.

摘要： The present invention provides a programmable generic read channel control device and circuitry for generating an output signal to control read/write operations. The programmable generic read channel control device includes a set of extension timer, a set of configuration registers, a set of AND gates, and an OR gate. The extension timers are programmed to generate a set of pulses of programmable width in response to a read gate and write gate signal. Each of the pulses is defined by a leading edge pulse and a trailing edge pulse. The set of extension timers includes a short write gate extension timer configured to generate a write gate short leading edge pulse and a write gate short trailing edge pulse defining a write gate short pulse width. The configuration registers store a set of configuration data for the pulses with each configuration register storing one configuration data for either a leading edge or a trailing edge pulse of one of the pulses. The configuration data indicates whether the associated pulse is enabled. The AND gates are arranged to receive the pulses of programmable width with each AND gate receiving either a leading edge or a trailing edge of one of the pulses as a first input. Each AND gate also receiving a configuration data as a second input that allows the first input to be transmitted as an output signal when the configuration data at the second input is enabled. The OR gate is arranged to combine the output signals from the set of AND gates to generate the output signal such that the output signal is generated from only the leading or trailing edges of the pulses from the AND gates receiving the enable signals.

摘要： The present invention provides a programmable ADC with bit conversion optimization and method therefor. The programmable ADC includes an amplifier, a programmable clock generator, a comparator, a successive approximation logic, a digital-to-analog converter, and a voltage converter. The amplifier is arranged to sample and hold an input analog signal to be converted into N digital data bits. The programmable clock generator generates a clock signal for each of the N-bits to trigger setting of one of the N-bit digital data bits such that each of the N bits is set during a time optimized for each bit. The comparator is coupled to receive and compare the input analog signal with a successively approximated analog signal to generate a digital output signal. The successive approximation logic is configured to successively set each of the N-bits in response to the digital output signal and the clock signal to generate a successively approximated N-bit digital data. The digital-to-analog converter converts the successively approximated N-bit digital data into a successively approximated analog current signal. The voltage converter has a resistance value for converting the successively approximated analog current signals into the successively approximated analog signal for input to the comparator. The voltage converter is arranged to optimize a time constant defined by the resistance and an output capacitance of the digital-to-analog converter.

摘要： A circuit is provided for realizing multiple precision resistor elements on an integrated circuit by sensing a reference resistor. The circuit contains a first current source which passes a first current through a reference resistor located either on or off of the integrated circuit to generate a reference voltage. The reference voltage is applied to the inverting input of a precision high gain operational amplifier. A second current source is connected to the drain of a first MOS transistor operating in its ohmic region. The second current source is also connected to the non-inverting input of the high gain operational amplifier. The output of the operational amplifier is electrically connected to the gate of the first and second MOS transistors. In operation, a precision resistance is developed across the second MOS transistor which is equal to or some determinable multiple of the resistance of the reference precision resistor located on or off chip. An operational amplifier adaptable to this circuit is also disclosed.
