ABSTRACT:
A delay circuit includes a semiconductor chip; a first inverter array formed on said semiconductor chip so as to have a number of first inverters so that it provides a number of delay signals; a second inverter array formed on the semiconductor ship so as to have second inverters, each having the same configuration as that of the first inverters, which are connected to form a ring counter; a phase locked lead-in unit for determining a phase difference between an oscillation output of the second inverter array and a basic clock and converting it into a voltage which is applied as power voltage to the first and second inverter arrays.
