Li, Shenyang (author)This thesis describes the design of a 3rd order 1-bit delta-sigma modulator whose input-signal range (0 to 1.95V) exceeds its supply voltage (1.2V). By using a passive input stage and a single-OTA resonator, this beyond-the-rails modulator realizes a 3rd order loop filter with only two amplifiers instead of the usual three and thus achieves...master thesis 2023

Chakravarty, Saurabh (author)Photovoltaic (PV) modules have considerable difficulty when exposed to shading since even partial blockages can significantly reduce energy production. To make the PV module shade-resilience, sub-module maximum power point tracking(MPPT) can be done for each string in the module. One way of doing it is by using converters at the sub-module level...master thesis 2023
