A compound current cell, with n-type, p-type, and bipolar properties, is proposed in this brief and utilized in a current-steering digital-to-analog converter (DAC) to satisfy the application of rail-to-rail voltage sources. In addition, the DAC with cells also has a high-speed fashion. Therefore, this brief presents a 6-bit CMOS current-steering DAC with(More)
This study presents a 6-bit 2.7 GS/s low-power digital-to-analogue converter (DAC) for ultra-wideband transceivers. A ‘2(thermometer)+ 4(binary)’ segmented architecture is chosen to reach a compromise between the current source cell’s area and the operating speed of the thermometer decoder. In addition, the proposed pseudo-thermometer structure improves the(More)
