A CMOS temperature-independent current reference with novel superposition structure is presented, which uses a third branch extent to optimize the temperature features by curvature ctmapensation. Devdoped for an AC/DC converter, the current reference is implemented in 0.6μm CMOS technology, which is simulated temperaaae coefficient of 16 ppm/℃ in the temperature range from- 40℃ to 135℃ and 77.2dB of simulated power supply rejection ratio (PSRR).
