Abstract
A current source having two current paths connected as current mirrors with an amorphous material device in one of the current paths which is electrically alterable from a high impedance state to lower high impedance states without switching to a low impedance state. A diode interconnects the amorphous material element to the current path to prevent damage to the current path during electrical alteration of the amorphous material device. The current source is included in a differential amplifier and operational amplifier to provide fine incremental trim or offset adjustment.
