摘　　要：本文提出了一种用于Buck变换器的带隙基准电压源,该电路结构简单,性能可靠,可移植性好。当温度在-40℃~125℃范围内变化时,基准电压的典型温度系数为7.3ppm/℃。本设计采用0.6μm HVCD工艺进行仿真验证,Hspice仿真结果表明该带隙基准电压源能够满足Buck变换器系统的需求。A bandgap reference that can be used in Buck converter is proposed. This bandgap reference circuit with simple structure is reliable and easy to be transplanted to other applications. In temperature range from-40℃ to125℃, the typical temperature coefficient is 7.3ppm/℃. This work is implemented in 0.6 μm HVCD process. The Hspice simulation results show that the proposed circuit works well in Buck converter and can meet the need of the converter system as a whole.
