Research Area

IMICL researches mixed-signal integrated circuit design. The major research topic is data converters, which converts analog signal to digital signal or vice-versa (i.e. ADC and DAC). The data converters are required not only for ultra high-spped communication systems such as PCIe gen, SerDes, WLAN and 5G network, but also for sensor, audio, automobile, and medical devices. For these applications, our research focuses on designing high-speed, low-power, and compact data converters. The main research areas in detail are as follows: 

• Giga S/s single channel analog-to-digital converters (ADC) using flash, SAR, pipeline architectures.  

• Tens of Giga S/s Time-Interleaving architectures.

• Mismatch calibration algorithm to compensate for offset, gain, and time-skew errors.

• Novel data converter architecture using time-domain, current-domain, and hybrid technologies. 

• High-resolution data converters using noise-shapping method.

• Input and clock network design with wide BW.
