Abstract
A differential inverter such as may be used in an oscillator circuit. The differential inverter is connected between first and second current sources. The differential inverter includes first and second single signal CMOS inverters connected in parallel between the first and second controlled current sources. Each of the current sources is a MOS transistor. A bias circuit is connected to the control gates of the MOS transistors and provides bias signals thereto, the bias circuit includes a variable current source with bias signals being generated in response to the current flow in the variable current source.
