In this paper, a standard cell low power 4-bit flash analog-to-digital converter (ADC) is proposed. The converter utilizes comparators created using only logic gates for converting analog input signals to digital values. This novel flash architecture consists of several CMOS gates with inputs connected to a common input node or to one of the supply lines. Depending on the relationship between the...
This paper presents a novel all-digital circuit topology for a digital-to-analog converter (DAC). It consists of series of inverters whose outputs are connected together. Depending on the thermometer code input, some inverters will have conducting PMOS whereas others will have conducting NMOS, thus providing an analog output. Even though the system is inherently non-linear, mathematical optimization...
