| Zusammenfassung: | A variable gain amplifier to output a differential output signal includes an input circuit to input a differential input signal, a buffer circuit to buffer the differential output signal to a common mode voltage, a compensation circuit to compensate the differential output signal to prevent variation in the differential output signal, and a comparison circuit to compare the common mode voltage to a predetermined voltage and to adjust the common mode voltage to equal the predetermined voltage. |
