(TU Delft Electronic Instrumentation) Pan, S. (TU Delft Electronic Instrumentation; Tsinghua University) Makinwa, K.A.A. (TU Delft Microelectronics) Department Microelectronics Date 2023 Abstract BJT-based temperature sensors are widely used because they can achieve excellent accuracy after 1-point calibration. However, they typically dissipate mu textWs of power and require supply voltages above 1V [1]. Although sensors based on DTMOSTs [2], [3], capacitively biased (CB) diodes and BJTs [4,5] have demonstrated sub-1V operation, this comes at the expense of accuracy. This paper presents a sub-1V CB BJT-based temperature sensor that achieves a 1-point-trimmed inaccuracy of 0.15°C (3σ) from -55 circC to 125 circC, which is 4times better than the CB BJT state-of-the-art [4]. It also achieves a resolution FoM of 0.34pJ.K2, which is 6.8 times better than that of state-of-the-art BJT-based sensors with a similar accuracy [1], [6], (Fig. 23.5.6).
