Design of Low-Voltage Wide Tuning Range CMOS Multipass Voltage-Controlled Ring Oscillator
(2011-04-08)This thesis introduces a multipass loop voltage controlled ring oscillator. The proposed structure uses cross-coupled PMOS transistors and replica bias with coarse/fine control signal. The design implemented in TSMC 90 nm ... -
AN ENERGY-EFFICIENT, HIGH SPEED CLASS-E TRANSMITTER FOR BATTERY-FREE WIRELESS SENSOR NETWORKS
(2020-02-18)Energy efficiency and power consumption are increasingly important in wireless communications and especially for wireless sensor networks (WSNs). The limited energy budget in a WSN imposes many constraints on the transmitter ... -
Miniaturizated Respiratory Monitoring: Synchronous Demodulation & Bi-Directional Ultrasonic Flow Sensing
(2023-08-28)The issues surrounding optimization of respiratory monitoring are of size, power, and SNR (Signal to Noise Ratio). Miniaturization and optimization of components within a respiratory monitoring system is valuable for ... -
Next Generation Adaptive Optics
(2020-11-19)Adaptive Optics (AO) is an integral part of modern astronomy. Current systems are pushing the limits of large diameter telescopes to achieve near diffraction limited performance. Historically, AO systems have been limited ... -
Techniques for enhancing the performance of bulk-driven circuits in nano-scale CMOS technology
(2014-12-10)Bulk-driven (BD) technique has been proposed to remedy the voltage swing limitation problem in modern CMOS technology. However, challenges exist when the CMOS technologies move to the nanometer-scale. The goal of this ...
