ABSTRACT:
An input-stage amplifier (10) operating on a supply voltage (Vdd) and an output-stage amplifier (20) operating on a supply voltage (Vamp) are supplied at the non-inverting input with half the supply voltage as a reference voltage Vref. This allows the output level of the amplifier (10) and the input level of the amplifier (20) to be the same (Vref), thereby allowing connection therebetween via a resistor (21) without any capacitor. Further, resistors (22, 23) connected between the inverting input and the output of the amplifier (20) and between the inverting input and ground potential, respectively, are controlled such that the resistances satisfy R22/R23=Vamp/Vdd−1. This makes the output level of the amplifier (20) equal to Vamp/2.
