Frequency compensation of an amplifier including at least two gain stages
The circuit has an amplifiers (TE) receiving a signal, and amplifiers (TI, TS) provided downstream of the amplifier (TE). A unit gain amplifier (B) receives the signal and provides another signal relating to a low impedance copy of the signal. An amplifier (TS`) has an output and an input connected...

| Zusammenfassung: | The circuit has an amplifiers (TE) receiving a signal, and amplifiers (TI, TS) provided downstream of the amplifier (TE). A unit gain amplifier (B) receives the signal and provides another signal relating to a low impedance copy of the signal. An amplifier (TS`) has an output and an input connected to an output terminal and an output of the amplifier (B) via a capacitor (C1), respectively. A transconductance amplifier (TI`) has an input and an output connected to an output of the amplifier (B) via a capacitor (C1`) and to an inlet of the amplifier (TI), respectively. An independent claim is also included for a method for amplifying a signal. |
