This paper proposes a dynamic voltage frequency scaling technique (DVFS) for a CMOS differential bootstrapped ring-voltage controlled oscillator (DBRO), implemented in a 3-stage cross-coupled charge pump (CC-CP), for energy harvesting (EH) applications. A circuit applying this technique known as spl...
