Power Management Integrated Circuit Design
Power management circuits and techniques are critical for improving energy-efficiency, reducing heat dissipation, and extending the battery life for mobile and embedded applications.
Capless analog low-dropout regulators (LDO) and digital LDOs [US Patent 1], [US Patent 2], [ICECS'10], [Book]
Light-load efficient and wide-dynamic range DC-DC converters [MWSCAS'09, GoMACTech'11]
Energy harvesting Interface, e.g., Thermalelectric generator (TEG)
Ultra low-quiescent current analog IPs. [ICECS'11]
Hardware Security and Assurance
Mathematically secure cryptographic algorithms may leak side-channel information when implemented on an FPGA or ASIC. Detecting side-channel attacks are hard because they are passive. Power/EM side-channel attack countermeasures may incur heavy power, performance, and area overhead.
Real-time power side-channel attack detection circuits. [ISCAS'21a], [ISCAS'21b], [MWSCAS'21]
Leveraging on-chip voltage regulators for power/EM side-channel attack countermeasures.
