This paper describes a time-domain temperature sensor based on a successive approximation algorithm. Without using any bipolar transistor, a temperature sensor composed of a temperature-dependent delay line (TDDL) is utilized to generate a delay proportional to the measured temperature. A binary-weighted adjustable reference delay line (ARDL) is adopted with an effective delay varied by a SAR control...
The first time-domain successive approximation register (SAR) smart temperature sensor is proposed in this paper. Without using any bipolar transistor, a temperature sensor composed of temperature-dependent delay line is utilized to generate a delay time proportional to the measured temperature. A binary-weighted time reference delay line is adopted for set-point programming. The effective delay of...
