作者君跑了startup。 因为这次的application说好了,supply voltage已经settle好了,SOC才会enable我们这个frontend,所以作者君就跑了一下transient的enable(第一个图里的ENB开关们全部由导通变成断开),结果…… VPS就是第一个图里最上面那个PMOS的gate Voltage,也就是opamp的输出。横坐标是时间,纵坐标是电压。VDD是1V。
A start-up circuit for a bandgap reference circuit include an operational amplifier and a diode coupled to a second input terminal of the operational amplifier. The circuit includes a first current branch including a first transistor and a second transistor in series, for generating a first ...
A start-up circuit for a bandgap reference circuit includes a sampling circuit for sampling current through a diode in one of first and second diode/resistor networks that respectively provide complementary PTAT and CTAT characteristics in the bandgap reference, and a current injection circuit to inj...

首先介绍经典1.25V BGR。 Va和Vb被运放钳位,所以相等。所以dVf=Vf1-Vf2 I1R1=I2R2 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…
