title = "A Dual-Output Picowatt Hybrid Voltage Reference with Digital Trimming Technique",
abstract = "This paper presents a dual-output picowatt voltage reference in hybrid topology for ultra-low power IoT systems where multiple reference voltages are required. A digital trimming technique for two output voltages is investigated to compensate for process variations. A stacked structure of self-regulation native NMOS is implemented to improve PSRR and line sensitivity. The circuit is designed in a 180-nm CMOS process with a silicon area of 13,900 µm2. Untrimmed post-layout simulation results show that the circuit achieves two constant output voltages of 704.7 mV and 1146.5 mV with temperature coefficients of 92.2 ppm/°C and 38.2 ppm/°C, respectively, from 0° C to 125° C while consuming 278.9 pA. The low output voltage achieves a line sensitivity of 0.004\%/V, a PSRR of -69.6 dB at 100 Hz, and a variation coefficient of 1.81\%. The high output voltage achieves a line sensitivity of 0.003\%/V, a PSRR of -67.2 dB at 100 Hz, and a variation coefficient of 0.46\%.",
