Year: 2026
Type: article
Abstract: This paper presents a low-area, low-temperature coefficient (TC) CMOS voltage reference (CVR) circuit utilizing a compensation technique. Compared to traditional CVR circuits, this design does not rely on compensating the temperature characteristics of the threshold voltage. It lowers current demand, reducing resistor dependency and thus minimizing circuit area. In addition, a curvature compensation circuit is constructed, improving temperature stability. Implemented in 180 μm CMOS the core area of the circuit is 0.0081 mm2. Under a 1.8 V supply voltage, post-layout simulations show that the best TC reaches 1.06 ppm/°C over the temperature range of −40 °C to 125 °C, and the line regulation (LR) is 0.36%/V within a supply voltage range of 1.6 V to 2 V.
