The variation of temperature is detected by a PTC resistor that determines the reference current of a bootstrapped cascode source. This current is used to bias an active inductor. The self-resonance frequency varies accordingly to the shift of the current, thus providing the temperature to frequency conversion. The circuit has been implemented using a standard 65 nm CMOS technology. A frequency of oscillation of 31.3 MHz at 20°C has been obtained, with an estimated sensitivity of 50.5 kHz/°C, a resolution of 0.12°C and a power consumption of 21.8 uW within the 0-80°C temperature range.||URI:||http://hdl.handle.net/10553/47598||ISBN:||9781479957439||DOI:||10.1109/DCIS.2014.7035580||Source:||Proceedings of the 2014 29th Conference on Design of Circuits and Integrated Systems, DCIS 2014 (7035580)|
