摘　　要：基于BiCMOS工艺下研制一种单片式多功能集成电路汽车电子电压调节器。采用具有温度补偿特性的基准电压源代替稳压二极管来提供交流发电机输出取样电压。调节器设计成单片CMOS集成方式,减小了调节器的体积,使其可以和交流发电机制作在一起,提升了调节器的稳定性,提高了整车供电质量,有效延长了汽车电子设备的使用寿命。Spice仿真结果表明,该芯片完全达到所要求的技术指标。Single-chip multi-function automotive IC voltage regulator is designed based on BiCMOS technology.It uses a temperature compensated reference voltage regulator to replace the alternator output diodes to provide the sample voltage.The regulator is designed into single-chip CMOS integrated approach,which reduces the volume so that it can be produced together with alternators,enhances stability of the regulator and improves quality of the vehicle power supply,effectively extends the life of automotive electronics.Spice simulation results show that the chip fully meet the required specification.
