（1）当R1=93K时，IREF=10μA，VREF=0.943V。随着R1增大，VREF先增大，再减小，最后几乎保持不变。随着R1增大，IREF随之减小。

（2）当R1=93K，R2=1K时，IREF=10μA，VREF=0.943V。随着R2增大，VREF和IREF随之减小，后几乎保持不变。

（3）当R1=50K，R2=1K时，IREF=19μA，VREF=0.943V。随着R2增大，VREF和IREF随之减小，后几乎保持不变。

（4）当R1=10K，R2=2K时，IREF=125μA，VREF=1.25V。随着R2增大，VREF和IREF随之减小，后几乎保持不变。

（5）当R1=90K，R2=2K时，W5=3.93u，IREF=13.82μA，VREF=1.25V。随着W5增大，VREF和IREF随之减小，后几乎保持不变。

(6)当R1=90K，R2=2K，W5=4u，W6=21.96u时，,IREF=13.91μA，VREF=1.25V。随着W6增大，VREF和IREF随之增大，后几乎保持不变。

(7)当R1=90K，R2=2K，W5=4u，W6=22u，W3=2u时，,IREF=13.91μA，VREF=1.25V。随着W3增大，VREF和IREF随之增大，但增大的幅度较小。

(8)当R1=90K，R2=2K，W5=4u，W6=22u，W3=2u，W4=2u时，IREF=13.91μA，VREF=1.25V。随着W4增大，VREF和IREF几乎不变。

(9)当R1=90K，R2=2K，W5=4u，W6=22u，W3=2u，W4=2u，W1=20.23u时，IREF=14.03μA，VREF=1.25V。随着W1增大，VREF和IREF随之减小。

(10)当R1=90K，R2=2K，W5=4u，W6=22u，W3=2u，W4=2u，W1=20u，W2=23u时，IREF=14.01μA，VREF=1.25V。随着W1增大，VREF和IREF随之增大。
