Abstract:
A signal level conversion circuit 1 includes a first differential amplifier circuit 10 and a second differential amplifier circuit 20. The first differential amplifier circuit 10 multiplies a potential difference between a first input signal and a second input signal by G1 thereby providing an output signal. The second differential amplifier circuit 20 multiplies a potential difference between the output signal of the first differential amplifier circuit 10 and the second input signal by G2 thereby providing an output, where the two gains satisfy the relation of G1×G2
