摘要
A MOSFET isolation amplifier apparatus to allow stable high frequency linear operation of MOSFET power stages and to provide precise regulation of a load current through a magnetic yoke load. Variations of transfer characteristics and input parameters in the MOSFET power stages are corrected by use of a feedback signal which is generated in a current sense resistor by the load current. Such a power stage allows the implementation of isolation amplifiers which can provide high power high frequency linear regulation at elevated voltages and currents.
