Abstract: A novel current reference circuit based on current summing mode and TransLinear structure is proposed in this paper. To enhance the performance, the resistors are also optimized. With curvature compensated, the circuit is of high precision. The circuit is simply designed without operational amplifier. A pre-regulator is also included to improve PSRR. HSPICE simulation with 0.40 μm BCD process shows the temperature coefficient is 27 ppm/℃ in the range -40℃~125℃, the line regulation achieves 0.000 68%/V[7~20 V] at 25℃, and 12 V supply voltage, the quiescent current is 128.09 μA. As described above, the circuit is very suitable for the system of high voltage, low power consumption and high precision.
