abstract = "This paper presents an ultra-low-voltage (ULV) and ultra-low-power (ULP) voltage detector (VD) for energy harvesting systems (EHS). The VD is designed using a 2-transistor (2T) voltage detection circuit and a 2T bias circuit. By leveraging two types of transistors with small threshold voltage differences, the detection voltage is reduced to 240 mV, enhancing the feasibility and practicality of the design for ULV EHS. The detection voltage can be programmed by incorporating an appropriate voltage divider into the VD, while the proposed 2T bias technique reduces its variation across different process corners. The design is implemented in a 65 nm CMOS process and occupies a chip area of 260 μm2. Post-layout simulation results indicate that the VD achieves a detection voltage of 240 mV, with a standard deviation (σ) of 6.6 mV, drawing only 5 nA of current at a supply voltage of 0.3 V. The average temperature coefficient (TC) across five process corners is 33.8 μV/°C, simulated within a temperature range of -40 °C to 125 °C.",
