    • According to the present invention, the voltage of a battery is supplied to an electronic circuit such as a watch circuit through a step down circuit which is constructed of capacitors and switching MIDFETs. The step down circuit performs a current converting operation as well as a voltage converting operation. The operating current of the electronic circuit is reduced by the reduction in the operating voltage of the same. As a result that the operating current level of the electronic circuit is dropped and that the current conversion is performed by the step down circuit, the battery current is relatively largely dropped. The construction thus far described elongates the lifetime of the battery. According to the present invention, therefore, there is provided a circuit which is proper for driving the step down circuit.

    • A voltage detection circuit adapted for use in an electronic timepiece in which a source voltage from a battery power source, etc. is voltage-divided and applied to an input of a logic circuit including complementary MIS FETs so as to compare the divided source voltage with a reference potential level and to detect whether the source voltage is above a predetermined value or not. In the logic circuit, the logic threshold is set in the neighborhood of the threshold voltage of one MIS FET to establish a reference potential level. Advantages are provided in integrating the circuit in a semiconductor integrated circuit such that parameters relevant to the manufacturing processes do not influence the reference potential level very much and the dispersion in the detected voltage due to the fluctuations in the manufacturing processes are minimized.

    • 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.
