Abstract
A voltage-controlled delay element utilizes a current-starved inverter configuration with a feedback path that ensures a rapid discharge of the storage node to ground once the desired delay time has elapsed. The circuit comprises a circuit path for charging the storage node (preferably rapidly), a first pull-down path capable of discharging the storage node at a rate determined by the control voltage, a second pull-down path capable of rapidly discharging the storage node, an output inverter, and a feedback connection between the output terminal of the output inverter and the second pull-down path to rapidly discharge the storage node when the output voltage starts rising. The circuit further comprises a means for programmably adjusting the delay in response to logic signals.
