Description : Define junction field effect transistor (JFET) and give an example.

Answer : Junction Field-Effect Transistor: It is a semiconductor device having three terminals, namely Gate, Drain and Source, in which the current flow is controlled by an electric field set up by an external voltage applied ... : i) n-channel JFET and ii) p-channel JFET Examples of JFET: BFW 10, BFW 11 

Description : When does the Body bias effect occur in an n-channel MOSFET?  A) When the Source voltage is less the Bulk voltage B) When the Source voltage is equal to or greater the Bulk voltage C) When the Drain voltage is equal to the Bulk voltage D) When the Gate voltage is equal to the Bulk Voltage 

Answer : When does the Body bias effect occur in an n-channel MOSFET?  A) When the Source voltage is less the Bulk voltage B) When the Source voltage is equal to or greater the Bulk voltage C) ... voltage is equal to the Bulk voltage D) When the Gate voltage is equal to the Bulk Voltage 

Description : What is meant by body effect in MOSFET?

Description : Define α & β and derive the relation between (α) &) (β) of transistor.

Answer : α : The ratio of output collector current IC to input emitter current IE in the CB configuration is called current gain alpha (α).  β : The ratio of output collector current IC to the input base current IB in the CE configuration is ... ( 1/β) + 1  hence 1/ α = (1+β )/ β  Therefore, α = β /(1+β)
