Abstract
A new programmable CMOS bandgap reference circuit of high precision is proposed. The whole circuit was designed with 0.18um standard CMOS technology, and the simulation results show that the movement of reference voltage is 3.2mV while the temperature is range -40°C from 120 °C. The circuit has been successfully applied in 14-bit high speed DAC, while the output current range of DAC is 8-32mA.
