Abstract :
A precision operational amplifier is described which draws 12 μA of quiescent current and can operate from a 1.6-V supply while requiring no external components such as the usual biasing resistor. The amplifier has DC characteristics comparable to the industry standard OP-07 and AC characteristics as good as currently available micropower devices. The circuit has an input voltage range and an output swing which include the negative supply to facilitate its use in battery-powered and other single-supply applications.
