Question

Consider the circuit shown in the figure below :



If the op- amp is ideal with the output saturation voltage $V_{sat}=\pm 10V,$ then the transfer characteristic curve of the circuit can be drawn as

• A.
• B.
• C.
• D. None of these

Answer 1

The correct option is A

For the positive values of $V_{in}$, the transfer characteristic curve can be given as,




$where,V_{TH}=\frac{V_{sat}}{2}=\frac{10}{2}=5V$

For negative values, of input, the transfer characteristic curve can be given as,



$where,V_{TL}=\frac{-V_{sat}}{2}=\frac{-10}{2}=-5V$
