Mosfets & Regulators

Mosfets :(A) Depletion Type (B) Enhancement TypeBut in Laptop/Dekstops , Enhancement

Types are used.

Enhancement Type:(A) N-Channel (B) P-Channel

Importants :1. For V GS = 0 V, and V DS = some value , I D= 0 2. For Values of V GS less than the threshold

level,the drain current of an enhancement-type mosfet is 0 mA

P-CHANNEL MOSFET

Important Points:1.For Vgs <0 , current wll flow from source to drain
