Abstract:
An oscillator output circuit, comprising:a tank circuit receiving a digital oscillator signal having a signal period, the tank circuit oscillating with a resonant period which is less than the signal period; and a switch halting oscillation within the tank circuit for an interval equal to the difference between the signal period and the resonant period, wherein the oscillator output circuit may efficiently provide a high voltage amplitude signal, the tank circuit further including an inductor and at least one capacitor connected in parallel, wherein the switch shorts the inductor when a voltage across the at least one capacitor is zero, and the switch further includes: a diode connected to a first terminal of the inductor; and a bipolar junction transistor connected at an emitter to a second terminal of the inductor, at a collector to a cathode of the diode, and at a base to an input receiving a signal from the digital oscillator.
