Overlap capacitance
WebQuestion: Prob la: A common problem in amplifying weak signals is that the overlap capacitance of the amplifier (For example: the capacitance between drain and gate of the input device) is amplified by the “miller" effect and is seen as a load to the driver, often degrading the frequency response of the circuit. To mitigate this problem your friend … WebOverlap capacitance along source edge of gate Cov =LDWCox (Underestimate due to fringing fields) Department of EECS University of California, Berkeley EECS 105Fall …

WebThe capacitance is a result of the polarization of the medium due to electric field and the attraction of charges on one plate due to the charge on the other (as mediated by the electric field). When you have two plates facing each other, the electric field is present in their common area (ignoring small fringe effects).
