ABSTRACT:
A NMOS transistor in the input current path of a PMOS current mirror amplifier senses any tendency to change of the voltage across a load driven by the output current of the amplifier. In response thereto, the NMOS transistor changes the input current of the amplifier to thereby vary its output current in a sense to maintain the voltage across the load constant.
