Abstract
Utilization of a chip internal clock driver, for capacitive loads such as MOS circuits, which provides in response to an external clock phase adjustable and delayed secondary clock pulses. The delay circuit is an inverter circuit which uses a precharged coupling capacitor whose potential is dynamically increased (boosted) by capacitive coupling the input pulse to approximately twice the supply voltage and which capacitor is subsequently discharged by a constant current thus defining a delay time in a more extended and more precise range.
