Abstract
The timing circuit includes at least one delay element and its supply voltage is obtained from an active current source. The current source is a current mirror which is driven by a differential amplifier. The differential amplifier compares a voltage on the delay clement supply line to a voltage on a current control node connected to a voltage controlled current source. An RC compensating circuit may be coupled to the current control node.
