Abstract:Ring oscillator (RO)-based digital phase-locked loops (DPLLs) are very attractive for system-on-chip applications due to their tuning range, good phase noise property but suffer from compactness and power requirements. In this work, the concept of capacitive boosting as one of the key solutions which enhances the amplitude of oscillations of the RO is proposed, making it a suitable solution to the biomedical applications, specifically for medical implant communication system (MICS) band of operation ranging fr… Show more
