McqMate

Q.	What is the need for bootstrap biasing?
A.	to prevent a decrease in the gain of network
B.	to prevent an increase in the input resistance due to the biasing network
C.	to prevent a decrease in the input resistance due to the presence of multiple bjt amplifiers
D.	to prevent a decrease in the input resistance due to the biasing network
Answer» B. to prevent an increase in the input resistance due to the biasing network
Explanation: a bootstrap biasing network is a special biasing circuit used in darlington amplifier to prevent the decrease in input resistance due to the biasing network being used. capacitors and resistors are added to the circuit to prevent it from happening.
