Hi,
Can anybody please explain the feedback topology for the inverting opamp configuration. I cite the figure 8.26 from Razavi 3rd ed., an example given for voltage-voltage feedback. But I am confused about the mixing, from my understanding the voltage is sensed and the current is mixed at the input (is it voltage-current?).
Also about the input node of capacitive configuration, it is floating right? How to deal with this floating node?(Probably only with discrete circuits like SC circuits?)
