Design forLow Power Low Temperature Coefficient CMOS Voltage Reference Circuit

This paper presents a pure CMOS voltage circuit with compensation of VT (thermal voltage) and Vth (threshold voltage). Candance Spectre simulation with 0.34μm_Foundry18 process reports TC (temperature coefficient) is 1.98ppm/℃(-30℃DD) sensitivity of 0. 15% (V_DD=2. 5V-4. 5V). The output reference voltage is 552. 845mV (T=27℃,V_DD=3.3V). The dissipation is 21.85μw with V_DD=3.3V.
