A Self-Adjustable Clock Generator With Wide Dynamic Range in 28 nm FDSOI.

This work demonstrates a self-adjustable clock generator that closely tracks the voltage dependence of the critical path delay in a microprocessor. A tunable replica circuit (TRC) composed of inverter cells from the standard-cell library performs real-time frequency modulation to reduce the response time to a single cycle, and a digital controller quantizes the clock frequency by selecting appropr...
