    Question on slew rate of opAmp

    Okay ,everyone ! Think about what I am asking, and what the nonsense answer you give. I am so regret about you . I maybe find the anwer . In the book <the art of analog layout>, It is said that the lateral pnp transistor has a property that, when one collector of the split collectors is...

    Question on slew rate of opAmp

    It is said that , decreasing the transconductance of input stage will increase the slew rate of opAmp. So there is the structure shown in the picture. Q3-Q6 are in fact one split collector lateral pnp. By setting the collector area ration of Q3- Q6 to be 1:3:1:3, the collector currents and...
