Abstract:
An integrated circuit, comprising:an input terminal for feeding in an input signal to be amplified; an output terminal for outputting an amplified output signal; a terminal pad connected to said output terminal for outputting the output signal; a terminal for a reference-ground potential; and an analog amplifier having: a supply potential terminal; a first input-size amplifier section having a first signal path and an output; a second output-side amplifier section having: a second signal path, said first and second signal paths connected in series; a control terminal coupled to said output of said first input-side amplifier section, a drain terminal coupled to said output terminal and a source terminal directly connected to said terminal for the reference-ground potential; and a further transistor connecting said transistor to said supply potential terminal; a series circuit having a resistor, a capacitive element, a node between said resistor and said capacitive element, and ends, one of said ends of said series circuit connected to said output terminal, and another of said ends of said series circuit connected to said control terminal; and a further capacitive element connected between said mode and said terminal for the reference-ground potential.
