摘要： In an electronic timepiece having a primary frequency divider circuit coupled to receive a standard frequency signal and comprising a group of P-channel FETs and a group of N-channel FETs, a bias circuit supplies a bias input to the P-channel FET group and a separate bias input to the N-channel FET group. By providing these bias inputs through current mirror coupling from a standard current source, the response of the primary frequency divider circuit to low amplitudes of the standard frequency signal can be made substantially independent of timepiece battery voltage variations, over a wide range of battery voltages.

摘要： An inverting amplifier is provided with a high impedance input resistor connected at one end to an input terminal of the amplifier and connected at the other end to a first voltage source constituting a first binary logic level. The input terminal is also connected through a switch to a second voltage source constituting a second and opposite binary level. An MOS-FET has source and drain electrodes connected to the input terminal and the first voltage source respectively and a gate electrode connected to an output terminal of the amplifier. When the switch is closed, the second voltage is applied to the input terminal and the inverted output of the amplifier turns off the MOS-FET. When the switch is open, the first voltage is applied to the input terminal through the resistor and the inverted output of the amplifier turns on the MOS-FET. The low impedance of the MOS-FET in the turned on condition increases the stability of the amplifier under high humidity conditions.

摘要： 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.

摘要： 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.
