The traditional bandgap reference circuit was improved in the design, which includes the applying of self - bias structure and cascode structure, output of the opamp was used as self - bias voltage, saving bias circuit, and then it was helpful to get low power consumption. through using poly resistance of high value with low temperature coefficient, we reduced the influnce to circuit, if power supply did not change, we must decrease operating current to decrease power consumption, and increasing value of resistor could decrease the operating current efficiently. poly resistance of high value had large value of squared resistor, so we could save layout area
對傳統帶隙基準電路進行了改進設計，採用自偏置結構和鏡像電流鏡結構，利用運放的輸出電壓作為運放的偏置電壓，節省了偏置電路，降低了功耗;使用低溫度系數的多晶硅高值電阻，降低了電阻溫漂對電路的影響;在電源電壓不變的情況下，為了減小功耗就必須減小工作電流，而增大電阻的阻值能有效地減小工作電流，多晶硅高值電阻的方塊電阻很大，可以節省版圖面積。 -
