Question

Consider the figure shown below. If the saturation voltage of the op-amp output is same as the supply voltage, then the width of the hysteresis loop of the circuit (i.e UTP - LTP) will be__________V.

Answer 1

$V^{+}=\frac{V_0.2}{2+2}=\frac{V_0}{2}$

$when{V}^{+}>V^{-}\Rightarrow V_0=V_{OC}=12V$

$when{V}^{+}<V^{-}\Rightarrow V_0=V_{OC}=-12V$


$V_H=6(-6)=12V$
