| Zusammenfassung: | The invention discloses a differential current to voltage converter. The present disclosure provides systems and methods to provide a constant common mode voltage at the input terminals of a difference amplifier. A difference amplifier can receive an input signal and can deliver an amplified version of the received input signal at an output of the difference amplifier. In a system where a difference amplifier can receive an output of a digital-to-analog converter (DAC), the DAC performance can deteriorate in situations where common mode voltage at the input terminals of the difference amplifier are changing. A difference amplifier including feedback circuitry can provide a constant common mode voltage at the input terminals of the difference amplifier, leading to improved performance in asystem where the difference amplifier receives an input signal from a DAC.
本公开涉及差分电流至电压转换器。本公开提供了在差分放大器的输入端子处提供恒定共模电压的系统和方法。差分放大器可以接收输入信号并且可以在差分放大器的输出处传送接收到的输入信号的放大版本。在差分放大器可以接收数字转换器(DAC)的输出的系统中，在差分放大器的输入端子处的共模电压正在改变的情况下，DAC性 |
