ABSTRACT:
The present invention includes a plurality of FETs (211, 212, 213, 214, 215, 216, 217) including an operational amplifier with additional FETs (218, 219, 220,221) arranged as current mirrors, and a sense FET (101), and a current sensed at FET (101) is amplified, compared to a reference signal, the difference current derived from the amplified sense current and reference signal being amplified and provided at an output for use in control applications.
