Abstract

See full text

A voltage-controlled oscillator for generating oscillation signals at two output terminals includes an inductor coupled between the two output terminals, a capacitor coupled between the two output terminals, two P-type transistors, coupled between a supply voltage and the two output terminals, two N-type transistors coupled between a ground voltage and the two output terminals, and a control circuit. The control circuit is coupled to the inductor, and is arranged to control a current flowing through the two P-type transistors and the inductor by controlling a voltage of the inductor.
