Patent JP-S5851623-A (JP)
Title: Cmos circuit
Inventor: SUEHIRO MITSUTAMI
IPC: H01L27/092
Filed: 1981-09-24
Abstract: PURPOSE:To prevent both transistors(TRs) from being overlapped, by applying a signal to each gate, so that one TR is turned on and after a prescribed time another TR is turned on, in a CMOS inverter. CONSTITUTION:A P-CH MOSFETQ1 and an N-CH MOSFETQ2 constitute a CMOS inverter and an output Vout is taken out from a common connecting point of the Q1 and Q2. When a signal V1 applied to the gate of the Q1 goes to a high level, the Q1 is turned off but the Q2 is not immediately turned on to keep the off-state. After a time t1 is elapsed when the signal V1 changes to the high level, another gate signal V2 goes to a high level and the Q2 turns on. After the time corresponding to the pulse width of the signal V2 when the signal V2 goes to a low level, the Q2 is turned off, and the signal V1 goes to a low level after a time t2 elapsed and the Q1 is turned on. Thus, the overlapping of operation of both the TRs can be prevented, the increase in the through-current can be avoided, and the power consumption can be reduced.
