How does the frequency dependence of conductance and capacitance affect peaks?
Abstract: In this work, we describe how the frequency dependence of conductance (G) and capacitance (C) of a generic MOS capacitor results in peaks of the functions G/ω and - ωdC/dω. By means of TCAD simulations, we show that G/ω and -ωdC/dω peak at the same value and at the same frequency for every bias point from accumulation to inversion.
How do you calculate mutual capacitance between two conductors?
The mutual capacitance, C, between two conductors is defined as the amount of charge that can be stored on each plane, Q, per unit of voltage difference between the planes, V. The classical calculation of this capacitance is generally done by applying Gauss’s and Poisson’s equation for a given system.
What is mutual capacitance C?
The mutual capacitance C is defined as the ratio of accumulated charge Q and potential difference U between the bodies forming the capacitor C=Q/U. You might find these chapters and articles relevant to this topic. Tim Williams, in EMC for Product Designers, 1992

Transconductance
Transconductance (for transfer conductance), also infrequently called mutual conductance, is the electrical characteristic relating the current through the output of a device to the voltage across the input of a device.
