    • An input line carrying a square-wave voltage is connected through a capacitor to the drain and via an inverter to the gate of a MOSFET acting as a diode, the relative magnitudes of the drain and gate pulses being so chosen that the FET conducts during alternate half-cycles of the square wave whereby the capacitor is charged during nonconductive half-cycles and is fully discharged to the potential of the source of the FET during conductive half-cycles. If the source is biased by a constant voltage, a square wave in a higher voltage range is available at the drain. If the source is connected to potential through another capacitance, a d-c voltage is available at that electrode. Complementary MOSFET/diodes can be connected in push-pull or in cascade to amplify the input voltage; they may also be combined with supplementary voltage boosters including cascaded stages composed of ordinary diodes and capacitors. The MOSFET/diode may be part of an electronic clock drive.

    • To facilitate acceleration or deceleration of the stepping rate of a time-keeping counter responding to driving pulses from a frequency divider connected to a crystal-controlled oscillator, a succession of such driving pulses is taken from an OR gate with inputs receiving a basic pulse train .phi..sub..gamma. a normally present first ancillary pulse train .phi..sub..beta. spacedly interleaved with pulse train .phi..sub..gamma. and a normally absent second ancillary pulse train .phi..sub..alpha. with pulse positions offset from those of the other two pulse trains. To retard the timepiece, the pulses of train .phi..sub..beta. are blocked for a desired period; to advance it, pulses of train .phi..sub..alpha. are interpolated at a rate depending on the cadence of a series of control pulses selectively synthesized from a combination of low-frequency stage outputs of the frequency divider. Externally set selection signals are temporarily stored in a memory circuit including NOR gates with positive-feedback connections to inverting inputs thereof, the memory circuit being periodically tested by a resetting pulse recurring at a frequency lower than that of the driving pulses.
