ABSTRACT:
A high speed analog amplifier having a differential input and provides a single output signal which corresponds to the absolute value of the input voltage. Furthermore, the amplifier provides a selectable output offset voltage which is proportional to a selected reference voltage. Moreover, the reference voltage alone is sufficient to operate the amplifier, eliminating additional power supply connections.
