| Zusammenfassung: | The invention relates to a wide-area high-resolution programmable gain amplifier which is formed by connecting a first gain level and a second gain level with different gains in series. The second gain level can be used only for low gain and low power consumption. In addition, two pairs of chopper circuits are used for transferring flicker noise when the programmable gain amplifier is operated. |
