Abstract:
1. A D/A converter comprising: a D/A module for converting a digital signal to a first analog signal, wherein a first D/A module input is configured to receive the digital signal, a second D/A module input is configured to receive V a first differential amplifier for amplifying the first analog signal to a second analog signal, wherein the first differential amplifier comprises: a first resistive electronic component having a first terminal and a second terminal, wherein the first terminal of the first resistive electronic component is connected to the D/A module, and the second terminal of the first resistive electronic component is connected to the first input of the first differential amplifier; and a second resistive electronic component having a first terminal and a second terminal, wherein the first terminal of the second resistive electronic component is connected to the first input of the first differential amplifier, and the second terminal of the second resistive electronic component is connected to the output of the first differential amplifier, wherein the first resistive electronic component and the second resistive electronic component have substantially a same resistance.
