A new method for the removal of parasitic capacitances from sub-100nm MOSFETs using low-noise split capacitance-voltage measurements [PDF]
, 2011 The physical shape of MOSFETs and the processing involved in their fabrication give rise to parasitic capacitances. These capacitances are typically small compared to the intrinsic channel capacitance of the device, but as MOSFETs scale into the sub ...

A Simple and Non-Destructive Method to Measure Per-Terminal Baseplate Coupling of Power Modules
IEEE Open Journal of Power Electronics, 2023 The fast slew rates of wide bandgap semiconductors can produce common-mode currents that flow through the baseplates of multi-chip power modules. These currents increase the electromagnetic signature of these devices and force designers to reduce edge ...
