Beschreibung
Zusammenfassung:	A programmable gain amplifier (PGA) circuit for adjusting a signal gain between a signal input and a signal output can include a differential-input amplifier which can include a first input node, a second input node, and a first output node, where the differential-input amplifier can be configured to amplify a difference in signal level between the first input node and the second input node for being provided on the first output node. The PGA circuit can also include a first configurable input impedance circuit, which can be arranged between a first signal input node and the first input node, which can be configured to provide a first specified input impedance value. The PGA circuit can also include a first configurable feedback impedance circuit, which can be arranged between a first signal output node and the first input node, which can be configured to provide a first specified feedback impedance value.
