Tang, Z. (author), Pan, S. (author), Grubor, M. (author), Makinwa, K.A.A. (author)This article presents a sub-1 V bipolar junction transistor (BJT)-based temperature sensor that achieves both high accuracy and high energy efficiency. To avoid the extra headroom required by conventional current sources, the sensor’s diode-connected BJTs are biased by precharging sampling capacitors to the supply voltage and then discharging...journal article 2023
