| Popis: | A bandgap reference voltage source with a temperature coefficient adjustment block was proposed. The bandgap topology employs current summation and the circuit was designed through metaheuristic algorithms in a 0.35-mm CMOS technology. Simulations with typical parameters show that the designed circuit has temperature coefficient of 15 ppm/0C, line regulation of 263 ppm/V, and current consumption of 2.71 uA in 1.0 V power supply. An additional 3-bit temperature adjustment block allowed keeping the temperature coefficient values lower than 26.6 ppm/0C for 90% of the circuits, without interfering with the reference voltage output or line regulation values. |
