|---|---|---|
This paper presents a 400 MHz open-loop injectionlocked clock multiplier (ILCM) with low-power and fast settling time. A one-time DCO calibration and novel temperature compensation scheme guarantees PVT-robustness without the use of a power-hungry conventional frequency tracking loop (FTL). The compensated ring oscillator exhibits a frequency stability of 126 ppm/°C over the 0 to 55 °C temperature range. This suffices to maintain lock and meet MedRadio specifications as indicated from measurements taken from 20 test chips. The chip was fabricated in 180 nm CMOS and consumes 107 μW from a 0.7 V supply achieving state-of-the-art performance for PVT robust ILCMs operating at a comparable frequency range. |
