Negative threshold voltage

Mar With reference to the source terminal, if you start reducing your gate voltage from Vdd (exactly opposite to NMOS where you start your gate voltage from zero) to a point where you observe the channel inversion, at this point if you calculate Vgs and source being at the higher potential, you get a negative value. May( threshold voltage ) shift to the negative side in the.
