b. Figure-Q2(b)(i) shows an non-inverting Schmitt trigger comparator, while FigureQ2(b) (ii) shows the comparator's voltage transfer curve. The followings are two formulas related to the circuit: \[ \begin{array}{l} \text { UTP }=\operatorname{Vref}\left(\frac{R_{1}}{R_{2}}+1\right)-\frac{R_{1}}{R_{2}} V \text { sat }- \\ \text { LTP }=\operatorname{Vref}\left(\frac{R_{1}}{R_{2}}+1\right)-\frac{R_{1}}{R_{2}} V \text { sat }+ \end{array} \] i. Identify the op-amp's saturated output voltages. ii. Identify the hysteresis voltage of the comparator. [2] \( [2] \) iii. Calculate the resistance value \( \mathrm{R}_{1} \) and determine the reference voltage set in the comparator. [6] iv. Suggest a suitable voltage supply to ensure proper operation of the comparator.
