Description
Summary:A bandgap reference source with a temperature coefficient adjustment block was proposed. The topology employs current summation and the circuit was designed through a metaheuristic algorithm in a 0.35-um CMOS technology. Monte Carlo simulations show that the designed circuit has an average temperature coefficient of 27 ppm/°C, average line regulation of 428 ppm/V, and average current consumption of 3.1 uA in a 1 V power supply. The 3-bit temperature adjustment block allowed a maximum temperature coefficient of 26.6 ppm/°C for 90% of the circuits without interfering in the reference voltage output or the line regulation.
