摘要： A digital delay-locked loop has been discovered having a reduced area as compared to typical register-controlled delay-locked loops (RDLLs) used to control strobe delay lines that provide delay to strobe signals driving asynchronous FIFOs. This result is achieved by reducing ratio computation (i.e. gear logic) circuitry of the RDLL. A master delay line receives a control code to delay a reference clock by one clock period. A slave delay line receives the control code to delay a strobe signal by a predetermined fraction of the clock period. The master delay line may include individual sections responsive to the control code which effectively delay a signal by a portion of the clock period, the delay having a fixed relationship to a delay associated with individual sections of the slave delay line.

摘要： An apparatus for canceling an effect of power supply resonance is provided. The effect of power supply resonance is a variation in power supply voltage potential. This variation may substantially affect an output buffer by causing the output buffer's output to sag below desired values. A voltage regulating circuit is coupled to power supply lines local to the output buffer where the voltage regulating circuit is most effective in reducing voltage potential variation. An exemplary voltage regulating circuit is provided that uses charge-pumped capacitors to raise the power supply voltage potential when it falls below a desired value. A second example of a voltage regulating circuit uses charge-pumped capacitors to lower the power supply voltage potential when it rises above a desired value.

摘要： A method for quantifying effects of resonance in an integrated circuit's power distribution network is provided. The power distribution network includes a first power supply line and a second power supply line to provide power to the integrated circuit. Test ranges are selected for two test parameters, reference voltage potential of a receiver and data transmission frequency of the integrated circuit. At each combination of the two test parameters, bit patterns are transmitted by the integrated circuit to the receiver. A comparison is made between the transmitted bits and the received bits to determine whether the transmitted bits were correctly received. The comparison may be used to determine and report a range of values for the reference voltage potential and data transmission frequency that allow the transmitted bits to be correctly received.

摘要： A calibration and adjustment system for post-fabrication control of a delay locked loop charge pump current is provided. The calibration and adjustment system includes an adjustment device that varies an amount of charge pump current. Such control of the charge pump current in a delay locked loop allows a designer to achieve a desired delay locked loop operating characteristic after the delay locked loop has been fabricated. A representative value of the amount of adjustment desired in the charge pump current may be stored and subsequently read to adjust the delay locked loop.

摘要： A source synchronous interface determines an amount of delay for an incoming data signal and a phase offset for a latch device that latches the incoming data signal. A delay locked loop may be a dual loop delay locked loop, in which case, the loops may use a low jitter, local clock signal and an input clock signal that was transmitted with the data signal. The low jitter, local clock signal may provide a stable source from which to derive good clock signal edge transitions. The input clock signal may be used to determine the long term clock signal drift. A finite state machine within the dual loop delay locked loop may provide the necessary information for the amount of delay and the phase offset. The delay of the incoming data signal is produced by a digital delay line.

摘要： A SSTL memory interface pre-driver stage that uses a voltage regulator to generate a ‘virtual’ supply is provided. The ‘virtual’ supply, being lower than a power supply voltage of the pre-driver stage, allows low voltage transistors to be used, thereby improving interface performance and decreasing system power consumption. The pre-driver stage uses a biasing circuit to bias the voltage regulator, formed by a transistor arranged in a source follower configuration, to generate the ‘virtual’ supply off which a voltage translator stage of the pre-driver stage operates to generate an output of the pre-driver stage.
