摘要： A device includes an oscillator including at least one inductor and at least one capacitor and configured to generate, based on a positive supply voltage, an output signal oscillating in a resonance frequency of the at least one inductor and the at least one capacitor. The device further includes an oscillation detector configured to determine whether the output signal oscillates based on a clock signal and increase a loop gain of the oscillator until the output signal oscillates.

摘要： A wireless communication apparatus includes an oscillator circuit configured to generate an oscillation signal corresponding to an oscillation frequency determined by an antenna; and a bias generator circuit configured to reconfigure an operation region mode of a transistor included in the oscillator circuit by adjusting a bias signal in response to an enable signal.
