Abstract
An oscillator circuit generates an output frequency that is substantially independent of power supply and temperature variations. The oscillator circuit can be implemented using conventional complementary metal-oxide-semiconductor technology. The oscillator circuit is suitable for use as an internal oscillator for generating a stable reference frequency in telecommunication receiver modules.
