1. What is linear region in BJT or MOSFET. Is it ohmic region where voltage & current have linear relation or is it saturated region. I think linear means region in which there is linear relation between V & I.2. Active region?3. in MOSFET, in ohmic mode Vgs > vth and Vds < (vgs-vth) while in saturated mode Vgs > vth and Vds > (vgs-vth).When I apply 10V at Vgs with Vth=2V & Vdd=20V. Now I have noted Vds < 0.5V or it is typically drop across Rdson. According to above equation device since Vds< vgs-vth. It says its ohmic region but I thick device is saturated
4. In mosfet curve device switches between cut off - saturation or cut off - ohmic.
These are all good questions that are more appropriately answered by careful study by an electronics text book or other resources on the web.
