Assuming the diodes D1 and D2 of the circuit shown in figure

Home » Analog Circuits » Analog circuits miscellaneous » Question

Assuming the diodes D₁ and D₂ of the circuit shown in figure to be ideal ones, the transfer characteristics of the circuit will be

Correct Option: A

For V_i < 5 volts
D₁ is OFF, D₂ is ON then, the circuit will be drawn as,

KVL in loop (A) gives,
10 – 2I – 5 = 0
⇒ I = 2.5 A
and V₀ = 5 volts
For V_i > 5 volts, D₁ is ON and D₂ is OFF.
The circuit will be as shown below,

KVL gives,

I' =	V_i - 10
	2

and V₀ = 10 + 2I' = 10 + V_i – 10
⇒ V₀ = V_i
Hence, the transfer characteristics will be as shown in choice (b).
