Semiconductor device capable of trimming minimum delay time and maximum delay time of an output signal

摘要

In a semiconductor device capable of obtaining an optimum delay time, a plurality of delay circuits are connected in series to one another through points of connections between two adjacent ones of the delay circuits to produce a plurality of reference delay signals derived from the delay circuits. One of the reference delay signals is decided as the optimum delay time with reference to a practical condition. Thus, the delay time can be varied in the semiconductor device.
