Abstract

This paper proposes a current compensation system for dc offset in transmitting digital-analogue converter (auxiliary DAC) firstly, which solves the DC offset existing in DAC output current. It greatly enhances the flexibility of the output DC offset controlling and improves the consistency of output currents between the chips. The auxiliary DAC proposed by this paper can compensate the DC offset ranging from -2mA to 2mA with the regulation accuracy at 1.96 A, which achieves a high accuracy of output the compensation current.
