Abstract
A monolithic class AB operational amplifier with an extra output which supplies the difference between the mirrored supply currents is described. Such an operational mirrored amplifier (OMA) is a universal electronic building block particularly suited to the realisation of controlled current sources. The device, which contains a simulated p-n-p current mirror, has a bandwidth of 12 MHz and can supply a maximum output current of 20 mA.
