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 C

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