Dynamic, On-Chip Power Supply Grids
Mixed-signal SoCs include a large number of diverse system sub-components that are integrated together in a single nanometer CMOS chip, with each sub-components typically requiring its own independent, and well-isolated power supply. Moreover, with... | LEARN MORE
Low-Noise, Low-EMI Switching Power Converters
Switching power converters are highly desired in portable devices due to their high power conversion efficiency. However, the spurious switching noise and EMI they produce are quite problematic as they degrade the performance of noise-sensitive analog/RF circuits in these devices. | LEARN MORE
Energy-Harvesting Platforms
Many electronic devices, such as wireless sensor grids or implantable devices, operate in conditions where replacing or recharging batteries is unfeasible/uneconomical, and increasing the number of batteries to sustain the device for its intended operation time is either cost or size prohibitive. | LEARN MORE
High-Frequency Switching Power Converters
The off-chip passive components (inductors and capacitors) in conventional switching power converters are becoming increasingly difficult to accommodate in many electronic devices due to their high cost and large footprint. This difficulty is exacerbated... | LEARN MORE
Efficient Power Converters for Ultra Light-Load Applications and Highly Variable Operating Conditions
Switching power converters are known for their high power conversion efficiency, but they suffer for much lower efficiency at light loads, and their performance varies widely with operating conditions (i.e. input and output voltages), as well as the size of the passive components (i.e. | LEARN MORE
Welcome to PMRL
The Power Management Research Lab (PMRL) was established in 2009 by Prof. Fayed. Its research focus is in the area of power management and analog & mixed-signal integrated circuits. This includes integrated power conversion solutions for analog, RF and mixed-signal Systems-on-Chip (SoCs) and energy-harvesting applications, power conversion in SiC and GaN technologies, Nyquist-rate and oversampling data converters, and analog frontends for high-speed wireline transceivers. Please see our research and people pages for further details.
