Abstract
A delay circuit provides adjustable delay in constant increments. In order to achieve adjustable but constant delay times of a chain of inverter pairs, each pair is completed by a capacitor, a third inverter, and a transfer transistor the gate of which is fed by a voltage controlling the pair delay time. This voltage is generated by a control circuit measuring the actual delay time of the chain with respect to the period of a constant clock signal.
