Abstract: Circuits and methods for compensating variation in an amplitude-regulated oscillator are provided. In one example, the oscillator includes a diode clamp having back-to-back diode-connected transistors with body terminals. Circuits and methods modulate a body-source voltage of the diode-connected transistors to compensate for process, temperature, and voltage variation.
