Abstract
A signal level conversion circuitincludes a first differential amplifier circuitand a second differential amplifier circuit. The first differential amplifier circuitmultiplies a potential difference between a first input signal and a second input signal by Gthereby providing an output signal. The second differential amplifier circuitmultiplies a potential difference between the output signal of the first differential amplifier circuitand the second input signal by Gthereby providing an output, where the two gains satisfy the relation of G×G<0 and 0<−(G+1)×G<2.
