Abstract
An amplifier including first and second input transistors which are connected to respective first and second feedback amplification circuits associated with respective frequency-compensating capacitances. The second feedback amplification circuit has a two-stage structure and includes an internal compensating capacitance. The three frequency-compensating capacitances can have low values and can thus conveniently be integrated in the same chip as the amplifier. The amplifier can be used, in particular, as an interface between a zirconium-dioxide oxygen sensor and an electronic control unit which have different earth conductors.
