A neonatal temperature monitoring system operating in sub threshold regime that utilizes time mode signal processing is presented. Resistance deviations in a thermistor due to temperature variations are converted to delay variations that are subsequently quantized by a Delay measurement unit (DMU). The DMU does away with the need for any analog circuitry(More)
This paper presents a novel oscillator architecture that uses a low frequency temperature stable clock generated by a low power RC relaxation oscillator to improve the temperature stability of a low noise ring oscillator. Fabricated in 65nm CMOS process, the prototype oscillator consumes 197 to 452µW across an output frequency range of 45-to-75MHz.(More)
