ABSTRACT:
A CMOS oscillator including a first pair of series connected CMOS devices and second pair of series connected CMOS devices, a resistance connected to the source of one of said MOS devices of the first pair having a width to length ratio greater than the width to length ratio of the corresponding device of the second pair, and a series resonant frequency determining network. The resistance and the larger W/L MOS device determine the steady state operating current independent of other circuit elements. The gates of the one MOS device and corresponding MOS devices are connected to the drain of the corresponding device and the other MOS devices are connected as current mirrors.
