本文介绍了一种基于210nW BJT的温度传感器,在−15°C至85°C范围内实现了±0.15°C(3σ)的不准确度。双模前端(FE)结合了偏置电路和BJT内核,可将生成明确定义的CTAT(VBE)和PTAT(ΔVBE)电压所需的功耗减半。跟踪Δ ADC的使用降低了FE信号摆幅,并进一步降低了系统功耗。在180 nm BCD工艺中,原型在50 ms转换时间内实现了15 mK分辨率,转化为最先进的2.3pJK 2 FoM。
This paper presents a 210nW BJT-based temperature sensor that achieves an inaccuracy of ±0.15°C (3σ) from −15°C to 85°C. A dual-mode front-end (FE), which combines a bias circuit and a BJT core, halves the power needed to generate well-defined CTAT (VBE) and PTAT (ΔVBE) voltages. The use of a tracking ΔΣ ADC reduces FE signal swing and further reduces system power consumption. In a 180-nm BCD process, the prototype achieves a 15mK resolution in 50ms conversion time, translating into a state-of-the-art FoM of 2.3pJK2.
