temperature compensation of frequency references [1-5]. High resolution and energy efficiency are then critical requirements, the former to minimize jitter and the latter to minimize power dissipation in a given conversion time. A MEMS-resonator-based sensor meets both criteria [1], but requires two resonators. In principle, resistor-based sensors also meet these criteria, and are CMOS compatible, but previous designs have been limited by the power dissipation [2-4] or 1/f noise [6] of their readout electronics. This paper describes a CMOS temperature sensor that digitizes the temperature-dependent phase shift of an RC filter. It achieves 410μKrms resolution in a 5ms conversion time, while consuming only 160μW. This corresponds to a
