This proposal advances the development of effective power microconverters built in mainstream digital CMOS technologies without any modifications to the standard fabrication process. The study of high-voltage techniques for the co-integration of microconverters in low-voltage processes not only will avoid the fabrication complexity of high-voltage devices, it will also reduce the number of heterogeneous chips and discrete components. […]

  This proposal targets a fully-integrated power management circuit for a high efficiency class D audio amplifier in a standard CMOS process. The project will focus on optimizing efficiency, reducing cost, and enabling wide input voltage and load current handling well-suited for battery driven applications. The converter will operate directly from a battery to provide […]

  This project aims at designing and implementing an integrated control system for an audio power  amplifier system for portable devices, having good efficiency and sound quality. The proposed design controls a DC-DC converter to produce a varying power supply to a class AB output stage. The varying power supply tracks the input audio signal […]

This project aims at designing a high-efficiency DC-DC converter for TFT touch sensors. The main task of the converter is to step-up the low and variable input voltage to a higher and more stable voltage that is able to power the touch sensor. The most challenging part of the design is the regulation of the […]
