三极管电流电压公式(牢记):I=Is(e^(qVf/kT)-1),Vf就是Vbe,也就是射极与基极之间的电压,一般0.7V。Vf一般远大于kT/q=Vt,Vt叫做电子热电压,k是玻尔兹曼常数,T为室温,q是电子电荷量。Vt大概26mV。 所以简化为:I=Is*e^(qVf/kT) Vf=Vt*ln(I/Is) 于是Vf1=Vtln(I1/Is),Vf2=Vtln((I2/n)/Is)...

Bandgap reference circuits are used in a host of analog, digital, and mixed-signal systems to establish an accurate voltage reference for the entire IC. The most used CMOS implementation for voltage references is the bandgap circuit due to its high predictability, and low dependence of the supply...
In this paper, we present a low-voltage low-power CMOS bandgap voltage reference (BVR) based on the self-cascode self-biased op-amp. The current mirror mismatch error resulting from the channel length modulation (CLM) effect has also been compensated by using composite transistors. This proposed...
We present a pure CMOS bandgap voltage reference with a low quiescent current and high output current driving capability. The circuit sources a driving current of up to 1.5 mA with the reference voltage kept above 98.5% of its designated 1.2 V, and up to 6 mA before the voltage drops to ...
