Question

According to body effect substrate is biased with respect to

Answer 1

Body effect refers to the change in the transistor threshold voltage (VT) resulting from a voltage difference between the transistor source and body.Because the voltage difference between the source and body affects the VT, the body can be thought of as a second gate that helps determine how the transistor turns on and off.

Body bias involves connecting the transistor bodies to a bias network in the circuit layout rather than to power or ground.The body bias can be supplied from an external (off-chip) source or an internal (on-chip) source.

hope helps ☺️☺️
