Low distortion circuit with switched capacitors. |
摘要 |
A switched capacitor circuit (1) comprising an operational amplifier (OA), having first and second input terminals and an output terminal, the first input terminal being connected to a first reference potential, said operational amplifier (OA) being provided with a negative feedback network including a first capacitive element (C1) which is connected between the second input terminal and the output terminal of the operational amplifier, a second capacitive element (C2) which has a first terminal alternately connected to the second input terminal of the operational amplifier (OA) and to a reference potential, and a second terminal connected to a first circuit node (A) which is alternately connected to a signal input terminal (VIN) and said first output terminal (VOUT) of the operational amplifier (OA), the circuit (1) further comprising a third capacitive element (CX) connected between said circuit node (A) and a reference potential. <IMAGE>
