List the different capacitances of a MOS transistor.

Capacitances of a MOS transistor are

(i) Parasitic Capacitances or diffusion capacitances: Csb (Source to body capacitance) & Cdb (Drain to body capacitance)

(ii) Intrinsic capacitance: The intrinsic capacitance has three components representing the different terminals connected to the bottom plate are Cgb (gate-to-body), Cgs (gate-tosource), and Cgd (gate-to-drain).

(iii) Overlap capacitance: Cgsol (overlap capacitance to the source) & Cgdol (overlap capacitance to the drain)
