The advancement of high-speed communication has brought 5G technology to the spotlight. Amongst the various building blocks, Digital to Analog Converter (DAC) is one of it. Beyond 10-bit, fine resolution and accuracy of a DAC is challenging to achieve, especially with the small line-width technology and inaccuracy due to the systematic errors. One way to minimize this issue is the use of the digital technique that randomizes the thermometer code. The DAC digital input will enter the input registers together with the high-speed clock and converts into thermometer code. The signal will then be randomized before the data goes through the unary current sources. In this project, we will focus on the development of the digital randomizer block for a 12-bit DAC design.
