发明名称 Resonant oscillator circuit with reduced startup transients
摘要 Some embodiments of the present invention provide a system that implements a resonant oscillator circuit. This resonant oscillator circuit includes: a first inductor, a second inductor, a first capacitance, and a second capacitance, wherein the first and second inductors are configured to operate with the first and second capacitances to produce resonant oscillations which appear at a first phase output and a second phase output. The system also includes a startup circuit which is configured to start the resonant oscillator circuit in a state where: the first phase output is at a peak voltage; the second phase output is at a base voltage; and currents through the first and second inductors are substantially zero. By starting the resonant oscillator circuit in this state, the oscillations commence without a significant startup transient.
