Since real-world signals are inherently analog, converting them into digital format is essential for processing within digital systems. Our lab focuses on ADCs (Analog-to-Digital Converters) and DACs (Digital-to-Analog Converters), which serve as the critical bridge between the analog and digital domains. We specialize in the design of high-speed, high-resolution data converters, and serializer/deserializer (SerDes), including specialized high-performance converters for Low Earth Orbit (LEO) satellites.
To ensure accurate signal conversion, precise pre-processing and signal conditioning are required. This involves specialized components such as low-noise, low-distortion amplifiers and signal filters. We conduct research on high-performance analog front-ends (AFEs) characterized by minimal noise and distortion, which are fundamental to maximizing overall system performance.
As the complexity of integrated circuits grows, power consumption is rising rapidly, necessitating highly stable power delivery systems. Our research explores LDO (Low Drop-Out) regulators and DC-DC converters to address these power management challenges. Specifically, we focus on designing high-speed/high-current and area-compact LDOs optimized for silicon efficiency.
Processors play the most vital role in analyzing signals processed by analog and mixed-signal circuits. To overcome the bottleneck between memory and processor, we investigate computing-in-memory (CIM) circuits that enhance speed and energy efficiency. Our research focuses on developing high-performance CIM architectures with cell-level optimizations for these next-generation computing systems.
