RESEARCH

From any signal
to an ASIC system.

Next Generation Sensor Interface Circuit Design is our guiding philosophy. We start with the signal and the application requirements, then design the analog front end, data conversion, and digital processing as one integrated ASIC system.

01

Signal acquisition & digitization

Sensor interfaces & data converters

More details

We design analog front ends, sensor readout circuits, and high-speed, low-power ADCs and DACs as the building blocks of integrated ASIC systems.

  • High-speed ADC / DAC
  • Sensor interface
  • Wireline receiver
02

CMOS control & readout interfaces

Cryogenic quantum computing

More details

We develop CMOS circuits for cryogenic operation and integrated interfaces for qubit control and readout.

  • Qubit control & readout
  • Cryogenic electronics
  • Frequency synthesis
03

Silicon-based security

Hardware security

More details

We investigate chip-level reliability and security through physically unclonable functions and random number generation.

  • Side-channel protection
04

AI hardware & circuit optimization

AI & design automation

More details

We explore mixed-signal computing, processing-in-memory, and machine learning for efficient circuit design and optimization.

  • Mixed-signal computing
  • Processing-in-memory
  • ML-assisted design
