Mixed-Signal ICs combine analog and digital IC designs, including digital-to-analog converters (DAC), analog-to-digital converters (ADC), phase-locked loops, and clock recovery circuits. As data volumes increase, high-speed transmission interfaces require precise clock signals and high-speed DACs/ADCs to reduce signal distortions and latencies. To process massive volumes of data, DACs/ADCs must achieve high precisions, low power consumption, and high converting speed. Moreover, ADCs have various types, including pipelined ADC, successive-approximation ADC, and delta-sigma ADC. Research teams in the Institute of Electrical Engineering have been working on high-performance ADCs and have applied the ADCs in many fields, such as communications, sensors, fingerprint recognition, and radar systems.
