【摘要】 设计了一款用于直流电源变换器（regulator）的高性能带隙基准电路,电路结构简洁新颖,并具有输出参考电压可调的优点。Spectre仿真表明,在输入电压为3.3V±0.3V,输出约为288mV的典型应用中,当温度从-40℃～125℃变化时温度系数低至2.13×10^-6（ppm）K（TT工艺角下）,低频时电源抑制比可达78db更多还原

【Abstract】 A compact and well performance bandgap reference designed for DC-DC regulator are proposed.One of its advantage is the output voltage can be control easily.Spectre simulation shows that,while the converter has a 3.3 V±0.3 V input voltage and a 288 mV typical output voltage,temperature coefficient is as low as 2.13×10-6(ppm)/K(at TT corner),and the power supply rejection ration(PSRR) is as high as 78 db at low frequency.更多还原
