Abstract
In some embodiments, the invention includes circuit having a differential amplifier and body bias control circuitry. The differential amplifier includes a differential pair of first and second FET transistors to at least partially control output voltage signals responsive to input voltage signals, the first and second FET transistors being configured to be matched and having a body. The body bias control circuitry provides a body bias voltage signal to the body to place the first and second FET transistors in a forward body bias condition. The differential amplifier and body bias circuitry may be used in a sense amplifier, comparator, voltage controlled oscillator, delay locked loop, and phase locked loop as well as other circuits.
