| Zusammenfassung: | 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 a system where the difference amplifier receives an input signal from a DAC. |
