Question

4. Noise arising in JFETS, BJTs and other
complex IC amplifiers is generally described
by
(A) Two source input model
(B) Single source output model
(C) Two source output model
(D) Single source input model​

Answer 1

Explanation:

A i.e. two source input model

Answer 2

Answer:

The noise arising in "JFETS, BJTs" and other "complex IC amplifiers" is usually described by "two source input model".

Explanation:

• When JFETS and BJTs and other amplifiers that are meant in complex IC When was that arises in the jfet and BJT have an input model that has two sources.
• Hence this season amplifiers come under the two source input model.  
• These transistors come under bipolar three terminal semiconductors.
