Abstract
The present invention concerns a delay circuit that provides a fixed amount of delay that is generally independent of process variations. An input resistance is provided that may be presented to a threshold device, such as an inverter, that may then be presented as an output. The output of the threshold device may also be presented through a feedback path comprising a capacitive device to the input of the threshold device. The feedback through the capacitive load actively resists the movement of the load. As a result, the delay provided by the circuit is generally resistant to process variations.
