ABSTRACT:
A delay circuit that includes a logic gate through which an input signal passes, a capacitor configured to be charged and discharged at an output terminal of the logic gate and delaying the input signal, and a mirroring unit configured to constantly maintain current output by the logic gate by mirroring current output by a constant current source.
