Abstract
A first order of DWA (data weighted averaging) technique is proposed to improve 6-bit digital-to-analog convertor (DAC). In addition, this paper discusses the impact of mismatch between DAC unit elements. The simulation results show the effectiveness of the DWA technique in reduction of inband tones, also DWA technique proves its ability to solve DAC unit elements mismatch. The element mismatch noise is converted into a broadband. The mismatch elements noise is improved 9 dB if =0.01 with proposed DWA, thus improving the DAC performance if compared with DAC performance without using DWA circuit.
