Re: body effect
Dear Dude,
Body Effect
Normally the source and substrate must be at same potential. If it is P substrate then it must be connected to negative terminal if N substrates it must be connected to Positive terminal because the PN junction between the diffusion and substrate must be reverse biased. Then only it is possible to control the flow of current and Vt can be maintained. If not substrate reverse bias then PN is forward biased and Vt changes. This is termed as body effect.
