Advancements in VLSI Technology for Enhanced Signal Processing and Power Management in Electronic Systems
Main Article Content
Abstract
This research investigates the application of Delta-Sigma Modulator controlled switch-mode power supplies to
address the challenges associated with conventional PWM-controlled DC-DC Buck Converters. By exploiting the noise-shaping
capabilities of Delta-Sigma modulation, in-band tones in the output are mitigated. The study encompasses three phases: initial
design and performance evaluation of PWM-controlled converters, transition to Delta-Sigma Modulator control, and refinement
of the design to enhance efficiency and noise performance. Notable achievements include reducing inductor values and
integrating on-chip capacitors, leading to a peak efficiency of 91% at a 200MHz sampling frequency. Post-layout simulations
further validate the superiority of Delta-Sigma Modulator controlled switch-mode power supplies over PWM-controlled
counterparts.
