Frequency References for the IoT (Infineon)

• IoT devices need accurate frequency references (<500ppm) to control their sleep/wake cycles. These are traditionally based on bulky quartz/MEMs resonators. RC-based frequency references can achieve good accuracy while dissipating 100s of uWs [1]. The aim of this project is to design and implement an RC frequency reference that maintains this level of accuracy while dissipating significantly less power.
