  • Patent number: 11736075
    Abstract: An amplifier circuit is capable of switching between a unipolar output voltage domain and a bipolar output voltage domain. The amplifier circuit comprises an operational amplifier with a feedback circuit that is configurable using switches. By controlling the switches, the amplifier's feedback circuit can switched between two different arrangements having a positive and a negative signal gain, respectively. The amplifier circuit is designed such that the noise gain is the same in both operating modes, allowing a single noise compensation approach to be used for both operating modes. Since configurability of the circuit is achieved using static switches, the amplifier circuit maintains high accuracy and experiences no appreciable impact on power consumption as a result of implementing the switching.
