Title: On delay circuit for inverter
Inventor: YAMADA TETSUO
IPC: H02M7/48
Filed: 1989-03-22
Abstract: PURPOSE:To set or modify delay time easily and reliably through software by providing one clock, as a counting clock, based on channel data and setting frequency and count of the count clock respectively. CONSTITUTION:When count held in a latch circuit 1 is provided and gate signal rises, a counter circuit 2 starts counting with a counting clock signal (a) and produces a carry signal (c) upon count up. An FF 3 is set by the carry signal (c) and reset by the falling edge of gate signal thus producing a gate signal (d) which lags behind the gate signal (b) by a delay time. A multiplexer 6 receives a reference clock signal CKO, clock signals 1/2CKO, 1/4CKO, 1/8CKO from a frequency division circuit 5 and data from a latch circuit 4, and the multiplexer 6 outputs one clock signal as a count clock signal.
