Circuit for converting unipolar input to bipolar output |
摘要 |
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 feed-back 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. <IMAGE> |
