Q5.3: What is the modified AC output voltage ( $V_{o}(s)$ V_{o}(s) ) for the circuit shown in Figure 5.2 in L(s) domain? Choose the correct representation from the choices provided below:

Image failed to load

$V_{o}(s) = \dfrac{sR_{1}C_{f}}{R_{f}V_{in}(s)}$ V_{o}(s) = \dfrac{sR_{1}C_{f}}{R_{f}V_{in}(s)}

$V_{o}(s) = -\dfrac{R_{f}}{R_{1}}[\dfrac{1}{1+sC_{f}R_{f}}]V_{in}(s)$ V_{o}(s) = -\dfrac{R_{f}}{R_{1}}[\dfrac{1}{1+sC_{f}R_{f}}]V_{in}(s)

$V_{o}(s) = sR_{1}C_{f}R_{f}V_{in}(s)$ V_{o}(s) = sR_{1}C_{f}R_{f}V_{in}(s)

$V_{o}(s) = -\dfrac{R_{1}}{sR_{f}C_{f}}V_{in}(s)$ V_{o}(s) = -\dfrac{R_{1}}{sR_{f}C_{f}}V_{in}(s)
