ABSTRACT:
The circuit for converting unipolar input to bipolar output includes a differential amplifier, first and second feedback resistors; and a peak detector. The negative output of the differential amplifier is fed back to the positive input of the differential amplifier through the first feedback resistor, and the positive output of the differential amplifier is fed back to the negative input of the differential amplifier through the peak detector and the second feedback resistor. A pole of lowest frequency among feedback amplifier circuits forming the circuit for converting unipolar input to bipolar output is to be determined with cut-off frequency of an amplification stage of the differential amplifier.
