Classification: CPC H | IPC H

Claim 16:
17. A method comprising:
applying a differential input voltage to control terminals of input transistors through two current paths, one extending from a first input terminal formed by a terminal of a first input voltage protection transistor to the control terminal of one of the input transistors and the other extending from a second input terminal formed by a terminal of a second input voltage protection transistor to the control terminal of another of the input transistors;
controlling a gate drive voltage of the first and second input voltage protection transistors using a control current source and a control transistor coupled to the control current source;
controlling the differential input voltage using multiple feedback paths; and
compensating for leakage at the input transistors when the first and second input voltage protection transistors turn off.
