The reference is implemented in a 1μm pure CMOS process with Vtn≈|Vtp|≈0.7V at 25∘C using substrate pnp. A startup circuit, which shuts down itself after a controlled delay using Miller effect, is also introduced. By utilizing the body effect of the input transistors, the turn-on...
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…
