Abstract
An 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 and two N-type transistors. Source electrodes of the two P-type transistors are coupled to a supply voltage, and gate electrodes of the two P-type transistors are coupled to the two output terminals, respectively. Source electrodes of the two N-type transistors are coupled to a supply voltage, gate electrodes of the two N-type transistors are coupled to the two output terminals, respectively, and drain electrodes of the two N-type transistors are coupled to drain electrodes of the two P-type transistors, respectively. In addition, the drain electrodes of the two N-type transistors are coupled to two internal nodes of the inductor.
