摘要： An electric amplifier circuit for amplifying an output signal of a microphone comprises a supply input terminal (V10) to apply a supply potential (VDDA) for operating the electric amplifier circuit and a differential amplifier (110) having a first input terminal (E110a) for applying the output signal of the microphone (20), a second input terminal (E110b) and an output terminal (A110) for outputting an amplified output signal (OUT) of the microphone (20). A feedback path (FP) is provided between the output terminal (A110) of the differential amplifier (110) and the second input terminal (E110b) of the differential amplifier (110). A charge supplying circuit (120) is coupled to the feedback path (FP) to supply an amount of the charge to the feedback path (FP) in dependence on the supply potential (VDDA). The amount of charge supplied to the feedback path may be dependent on a change of the supply potential (VDDA).

摘要： An amplifier arrangement comprises an input transistor (MIN) being connected between reference potential terminals (VDD, VSS) by means of a current source (IB1) and a current sink (IS). An amplifier stage has an amplifier output (OUT) coupled to a first connection node (INSRC) between the current sink (IS) and a first terminal of the input transistor (MIN) by means of a feedback path (FB), and an amplifier input connected to a second connection node (INDR) between the current source (ID1) and the second terminal of the input transistor (MIN). A level-shifting structure (LSC) comprises a level-shifting element (VS) with one end connected to a reference connection, wherein the level-shifting element (VS) is adapted to perform a level-shifting of a potential at the second connection node (INDR) with respect to a potential at the reference connection. The reference connection is coupled to one of the following: the amplifier output (OUT), the first connection node (INSRC), a control terminal of the input transistor (MIN).

摘要： A signal processing arrangement (100) has a signal input (SI) for connecting a capacitive sensor (CS). An amplifier circuit (AMP) is coupled between the signal input (SI) and a feedback point (CB1). A loop filter (LF) is coupled downstream to the feedback point (CB1). A quantizer (QT) is connected downstream to the loop filter (LF) and provides a multi-bit output word (OW). The multi-bit output word (OW) consists of one or more higher significance bits (HSB) and one or more lower significance bits (LSB). A first feedback path (FB1) is coupled between a quantizer (QT) and the feedback point (CB1) for providing a first feedback signal to the feedback point (CB1) being representative of the one or more lower significance bits (LSB). A second feedback path is coupled to the quantizer (QT) for providing a second feedback signal to the signal input (SI) being representative of the one or more higher significance bits (HSB).
