| Zusammenfassung: | Disclosed are a multi-stage amplifier circuit, a method of operating a multi-stage amplifier circuit, and a device with the multi-stage amplifier circuit. The amplifier circuit technology includes an operational amplifier shared among multiple stages and switching circuitry. The various switching circuitry switches among elements to provide different input signals and different feedback to the shared operational amplifier at the different stages of operation of the amplifier circuit. The various switching circuitry also stores and discharges charge at one or more operational amplifier inputs. |
