Hints, Tips and Solutions<\/strong><\/h1>\n

Q: How can I get a CV curve of a MOSFET? And how can I get the current on all terminals?<\/strong><\/p>\n

A: There are two methods to get the CV curve of MOSFET, Small Signal analysis and Large Signal analysis.<\/p>\n

From the charge conservation, the sum of charge in the device must meet the charge neutrality relationship given by:<\/p>\n

Qg + Qd + Qs + Qsub = 0<\/p><\/blockquote>\n

so the Capacitance should be<\/p>\n
