Abstract
A driver circuit for providing reduced AC defects includes an output driver transistor with an effective compensation resistor coupled to a control input of the output driver transistor. An input signal is coupled to the control input of the output driver transistor through the compensation resistor. A current sensing detector is coupled between the compensation resistor and the control input of the output driver transistor for detecting an AC defect responsive to an applied input signal. A field effect transistor can be used for the current sensing detector. Also a differential amplifier can be used for the current sensing detector for detecting smaller AC defects.
