该论文提出了一种全集成、超低功耗的带隙电压和电流参考电路，仅消耗9.3nW功率，解决了传统参考电路在超低功耗实现中性能不稳定的问题。通过创新的电路设计，在极低功耗下实现了对工艺、电压和温度变化的强抗扰性。
have presented challenges in ULP implementation of reference circuits while keeping traditional requirements of stable performance. For voltage reference circuits, as an essential block in SoCs to generate various internal supply voltages, the bandgap voltage-reference (BGVR) scheme has been widely used since it provides a welldefined value with strong immunity to process/voltage/temperature variations. Nanowatt-consuming BGVR circuits have been recently proposed using a capacitor network [4] and a leakage-based proportional-to-absolute-temperature (PTAT) circuit [5]. On the other hand, the current reference circuit that is required to set internal bias current still presents difficulties in achieving both stable performance and ULP consumption. The general approach to building a current reference is to
