Oscillator circuit having voltage-withstanding mechanism

Abstract

An oscillator circuit having voltage-withstanding mechanism is provided. An inductor circuit is coupled to a pair of oscillating output terminals. A cross-coupled transistor circuit is coupled between the oscillating output terminals and a first terminal. A capacitor circuit is coupled between the oscillating output terminals. A first source degeneration circuit includes a first inductor, a first capacitor, a second capacitor and a first source degeneration circuit. The first inductor is coupled between the first terminal and a first power voltage. The first capacitor is coupled between the first terminal and a second terminal. The second capacitor is coupled between the first power voltage and a third terminal that is coupled to a second power voltage. The first source degeneration is coupled between the second terminal and the third terminal and is turned on based on a first feeding voltage.
