Abstract

In this article, a digital to analogue converter (DAC) based on multi-weighted current sources is proposed. This research requires only three kinds of current sources for a 6-bit DAC. The proposed DAC is implemented by 0.18m CMOS technology. The post-layout simulations of integral nonlinearity and differential nonlinearity are 0.076 and 0.099LSB, respectively. The core area of the chip is 640m 2. The DAC consumes 3.5mW at the sample rate of 1.6GHz with a supply voltage of 1.8V. The specifications of the proposed DAC make it suitable for a portable device.
