This work compares two major classes of voltage reference topologies: threshold voltage (V-T0)-based and (V-G0) bandgap voltage-based reference circuits. Four different topologies of voltage-reference designs with 1-V supply were designed and fabricated in 130 nm CMOS process. Monte Carlo ...
于是dVf=Vtln(n*I1/I2)=Vt*ln(n*R2/R1) 因此Vref=Vf1+I1R1=Vf1+I2R2=Vf1+dVf/R3*R2=Vbe+R2/R3*Vt*ln(nR2/R1) 一般忽略电阻的温度系数。文章中认为Vbe温度系数是-2mV/C,Vt是0.086mV/C,所以第二项系数需要是第一项的2/0.086=23倍,因此最终Vref=0.7V+23*0.026V=1.3V。 Sub 1V BGR 文...
