Abstract:
An amplifier comprising: a current mirror (CM1) having an mirror input terminal (X), a mirror output terminal (Y), a mirror control terminal (Z), and a common terminal (CT1); a differential transistor pair (DP1) comprising first (P1) and second (P2) transistors having respective control electrodes connected to receive an input signal, and having respective output electrodes coupled to the mirror input terminal (X) and the mirror output terminal (Y); a differential amplifier (A) having an non-inverting input (+) coupled to the mirror input terminal (X), an inverting input (-) to the mirror output terminal (Y) and an output coupled to the mirror control terminal (Z); and a capacitor (CP), characterized in that the capacitor (CP) is coupled between the mirror input terminal (X) and the mirror control terminal (Z).
