Design and Implementation of a 100MHz Low-Voltage RC Frequency Reference in CMOS Technology

הרקע לפרויקט:

This project involves the design and implementation of a compact 100MHz RC frequency reference in a 65nm CMOS process, operating at a low voltage of 0.6V. RC oscillators are essential in modern electronics as they provide a low-power, small-area alternative to bulky crystal oscillators without the need for costly off-chip components. The focus will be on achieving high accuracy and stability across a wide temperature range (-40°C to 125°C) with minimal long-term drift, making this design particularly suitable for space-constrained and low-power applications like IoT devices.

מטרת הפרויקט:

Success in this project could lead to tapeout and publication, offering an excellent opportunity for 4th-year students or those interested in continuing towards a master’s degree.
