    • A delay compensator circuit is disclosed to compensate for variations in temperature, supply voltage and process. A monitor circuit is further disclosed that allows the monitoring of the delay of a delay element. The delay compensator circuit and monitor circuit lend themselves easily to the ASIC design methodology since they use conventional ASIC building blocks; namely gates, memory elements and delay elements. The delay compensator and monitor use a time base to track variations in circuit parameters by monitoring the delay through a delay element (delay line or sub-circuit). Compensation may be achieved by switching delays in or out of the circuit to be compensated based on variations of temperature, voltage, and process as measured using the time base. The delay compensator permits the designer to control the output hold time independently of the output delay time. The delay compensator enables a latching device to hold the output signal for the required duration after a reference.
    • 公开了一种延迟补偿电路来补偿温度,电源电压和工艺的变化。 还公开了一种监视电路,其允许监视延迟元件的延迟。 延迟补偿电路和监控电路很容易适用于ASIC设计方法,因为它们使用传统的ASIC构建块; 即门,存储元件和延迟元件。 延迟补偿器和监视器通过监视通过延迟元件(延迟线或子电路)的延迟来使用时基来跟踪电路参数的变化。 可以通过基于使用时基测量的温度,电压和过程的变化来切换要补偿的电路中的延迟来实现补偿。 延迟补偿器允许设计者独立于输出延迟时间来控制输出保持时间。 延迟补偿器使得锁存装置能够在参考之后保持所需持续时间的输出信号。
