Question 1:
Considering the classical two stage Miller OTA, if I use MOS capacitor (an MOSFET with D S B terminals connected together) for compensation, which terminal should be connected to the output node, G or B? Is there any influence on the OTA if I exchange the two terminals casually?
Question2:
If I choose to apply the nulling resistor scheme to cancel the RHP zero existed in Miller OTA, and the nulling resistor is made by MOSFET woking in linear region. Is there any influence on the OTA if I exchange the position of the compensation capacitor and the nulling "resistor" casually? In other words, which of them should be connected to the output node of the OTA directly?
