    1. What is miller effect.
    2. Do it only applies in non inverting opamps where feedback cap is millerize into Cinput & cout.
    3. Or its an general effect which includes capacitance in high freq applications related to BJT , Fets etc, Like in Bjt at high freq cap across terminals is taken into effect.
    4. I was reading opamp book by GAYAKWARD, there while calculating effective input resistance of inverting amp, they millerize feedback resistor into two parts? So miller effect is on resistor also.
