The impedance seen at the source of diode-connected NMOS is lower when body effect is included, from 1/gm to 1/(gm+gmb), is strange for me.
Body effect increases the Vth, so Ids should decrease for same Vgs=Vds(diode connected). That means the impedance should increase, right?
How come it decreases?
