Abstract
In oscillators such as those used in electronic watches, low power consumption is quite desirable. To accomplish this, an oscillator is provided including a complementary inverter amplifier circuit comprising a complementary inverter including a p-channel MIS FET connected to a first source potential, an n-channel MIS FET connected to a second source potential, and the gate of the two FETs being applied with a common linear input. Respective load resistors are connected to the drains of the complementary FETs, an output being derived from the interconnection point of the load resistors or from the drains of the FETs. Further, a bias resistor is connected between the gate and the drain of each of the complementary FETs, the input being supplied to the gates of the FETs through respective capacitors. The p-channel FET and n-channel FET are individually biased so that the circuit may serve as a class B push pull amplifier of low power consumption.
