Abstract
An adjustable delay circuit for digital signals includes a series circuit which is disposed between two supply potentials and has at least a first transistor of a first conduction type and second and third transistors of a second conduction type. Control connections of the first and second transistors are connected to a signal input of the delay circuit. One connection of the first transistor, which is remote from the first supply potential, is connected to a signal output. A fourth transistor of the second conduction type is connected in parallel with the third transistor. A first control input is connected to a control connection of the third transistor and a second control input is connected to a control connection of the fourth transistor. The control inputs are used to adjust the delay time of the delay circuit.
