ABSTRACT:
A negative feedback high current driver for an in-circuit tester comprises a three stage amplifier for supplying a high current overdriving signal to a device under test. The high current overdriving signal substantially cancels out any remaining component of an in-circuit generated signal appearing at an input to the device under test.
