In actual IC manufacturing,the two plates of a MOSCAP is not symmetrical.generally,the bottom plate should be connected to gnd(the lowest voltage in a chip,NMOSCAP) or VCC(the highest voltage in a chip,PMOSCAP).as shown in picture1,G is the top plate and B/S/D is the bottom plate.
however,in the circuit of a integrator ,we need a cap which is connected between a input and the output as a feedback capacitor ,as shown in picture2 C1 and C2,so ,my question is : can i use the MOSCAP as the feedback cap?
