Abstract

PURPOSE: To attain low power consumption at oscillation by conducting a P- channel and an N-channel MOSFET at oscillation start in the oscillation circuit consisting of complementary MOSFETs so as to decrease the oscillation start time.
CONSTITUTION: Since a front gate comprising the P-channel MOSFET6 and the N-channel MOSFET7 is turned on/off by an input signal impressed to an input terminal In2, when a high level signal is given to the input terminal I22 at impression of power, the FETs 6, 7 are turned on to short-circuit resistors 1, 2. Thus, substrate bias effect is lost to the resistors 1, 2 and the oscillation stable time is reduced. When the oscillating state is stable and a low level signal is given to the input terminal I22, the FETs 6, 7 are turned off, and the resistors 1, 2 connected to the source of the P-channel MOSFET4 and the N-channel MOSFET5 increase the absolute value of each threshold voltage at the transition region due to the substrate bias effect so as to reduce power consumption at oscillation.
