Description: The purpose of this thesis is to develop a new generation of programmable analog-to-digital converters (ADCs) for digital controller of switch-mode power supplies (SMPS) used in low-power portable applications. The ADC is required to have a simple, low-power architecture, fast conversion period, programmable reference voltage and small on-chip area, all of which are very important for utilization of digital controller in miniature battery-operated devices. The proposed architecture consists of a windowed ADC based on delay-lines which quantize the converter output voltage within a window of the reference voltage. It also includes a Sigma-Delta digital to analog converter (DAC) architecture that provides programmable reference voltage for ADC where the inherent filtering effect of the delay-line is used to reduce the area and power consumption. The proposed architecture has been implemented on IC for three different portable applications and verified both through simulation and experimental results.
