** Sketch a basic AND circuit with to diode and explain its operation ? Explain how doping Increases the conductivity of Semiconductor ?

Ans :-    AND Gate :- It as two input terminals and one out put terminals.

Symbol :-

*** If two inputs are low out put is low. If one of input are is low out put is low If two inputs are high out put is high.

Explanation of " AND " Gates with two diode :-

*** Let D1 and D2 two diodes logical value " O " represent 0 and 1 represent 5v.

When A= 0 , B = 0 , Both diodes are forward bias current posses , voltage not formed A.B = 0.

*** When A=1, B= 0  or A= 0 , B=1
One diode forward bias , another reverse baise out put A.B = 0.

*** When A=B=1 Both diodes are reverse biase out put A.B=1.

Conductivity of Semiconductor when impurities are had to pure semi conductor. Then number charge careers Increase doping concentration the conductivity of Semiconductor Increase.
