Title: Oscillation output method
Inventor: HARA NAOHIRO
IPC: H03B5/32
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent an oscillation disabled state, when the oscillation output is outputted after the waveform is inverted by a 3rd CMOS inverter by forming a CMOS inverter of a 3rd stage into a 2nd inverter circuit which is packaged, independently of a 1st inverter circuit that has a CMOS inverter of a 2nd stage.

A 3rd CMOS inverter IV3 which is connected in series to the inverter IV2 is included in a CMOS inverter circuit IC2 that is independent of the circuit IC1 and consists of an independent package. When a power supply VDD is turned on and a crystal oscillator 10 is started, the fluctuations of the VDD is reduced compared with a conventional case, where the through currents simultaneously occur at three converters IV1 to IV3 even when the through currents occur at two inverters IV1 and IV2 due to the characteristic variance of manufacture, since the circuit 10 includes only the two inverters IV1 and IV2.
