ABSTRACT:
An electronic timepiece including a time-base signal source having a quartz vibrator operating at a frequency of 1 MHz or higher, and a multi-stage divider. At least one stage of the divider is comprised of a static induction transistor logic inverter (SITL inverter), which includes a static induction transistor (SIT) and a bipolar load transistor, operating at a bias voltage of or less than 0.5 volts. The time-base signal source may comprise an oscillator circuit which also includes a static induction transistor.
