Title: Sub-harmonic Pulse Injection Based Oscillator
IPC: H03K3/80
Filed: 2020-04-28
Abstract: Disclosed is a sub-harmonic pulse injection-based oscillator. The sub-harmonic pulse injection-based oscillator includes an oscillator unit and a pulse injection unit. The oscillator unit oscillates at a predetermined resonant frequency F_(OSC) to generate a sinusoidal oscillation signal. The pulse injection unit, based on the sinusoidal oscillation signal, generates an up-injection pulse and a down-injection pulse signal at a sub-harmonic frequency (F_(OSC)/N) of 1/N times the resonance frequency (where N is a positive integer of 2 or more), and generates a sub-harmonic pulse injection oscillation signal XO_(out) by respectively injecting an up-injection pulse and a down-injection pulse into the high peak and the low peak of the sinusoidal oscillation signal at each sub-harmonic period. Since the injection period of the up/down pulse is longer and the amplitude of the output oscillation signal can be reduced, energy loss due to parasitic resistance of the oscillator is reduced. The power supply voltage is also lowered, thereby enabling low-power oscillation.
