Abstract

The invention is directed to an amplifier including an absolute value circuit. The absolute value circuit may be driven by differential potentials and may include a first pair of transistors modulating a tail current of the amplifier when a differential input voltage goes high, and a second pair of transistors modulating the tail current of the amplifier when a differential input voltage goes low.
