|---|---|---|
This paper proposes a voltage reference operating up to 170 °C for low-power high-temperature systems. The proposed circuit buffers body voltages to avoid degradation of temperature coefficient from nwell/psub diode leakage. For low power overhead, it measures the diode leakage and adaptively adjusts the bias current of the buffers. This enables low power consumption at low temperature, which can allow an energy harvester to recharge a battery in the target system. Prototype chips, fabricated in a 180 nm CMOS process, show a ±3σ inaccuracy of 3.4% from 0 °C to 170 °C after single trim at 80 °C and a line sensitivity of 0.088 %/V from 1.8 V to 3.6 V. It consumes 76.3 pA at room temperature and 177 nA at 170 °C from 1.8 V. |
