Abstract
PURPOSE:To reduce current consumption while obtaining an extremely stable oscillation output at a frequency, obtained by dividing the resonance frequency of a quartz oscillator by an odd number, by connecting the quartz oscillator to the synchronized oscillating circuit composed of a C-MOS inverter and capacitor. CONSTITUTION:To obtain an oscillation output of frequency f0, resonance frequency fS of quartz oscillator Q is set to frequency (2+1).f0 obtained by multiplying frequency f0 by an odd number. The synchronized oscillating circuit, on the other hand, is set to oscillate nearly at frequency f0. Since the output waveform of the synchronized oscillating circuit shows a rectangular wave, a higher-harmonic component obtained by multiplying the oscillation frequency by the odd number appears. The higher harmonic of degree (2n+1) has a value close to resonance frequency fS=(2n+1).f0 of quartz oscillator Q, and consequently the higher harmonic is drawn into resonance frequency fS, so that the oscillation frequency of the synchronized oscillating circuit will be drawn into frequency f0.
