发明名称 RESONANT OSCILLATOR WITH OSCILLATION-STARTUP CIRCUITRY
摘要 Some embodiments of the present invention provide a system that implements a resonant oscillator circuit. This system includes a first inductor with a constant potential terminal coupled to an input voltage, and a time-varying potential terminal coupled to a first phase output. The system also includes a second inductor with a constant potential terminal coupled to the input voltage, and a time-varying potential terminal coupled to a second phase output. The system additionally includes a first n-type transistor with a source terminal coupled to a base voltage, a drain terminal coupled to the first phase output, and a gate terminal coupled to the second phase output. The system also includes a second n-type transistor with a source terminal coupled to the base voltage, a drain terminal coupled to the second phase output, and a gate terminal coupled to the first phase output. Finally, the system includes a startup circuit configured to commence oscillations in the resonant oscillator circuit by energizing the first inductor before energizing the second inductor.
