A bridge power amplifier is described in Exercise TYU 15.13. Using a computer simulation, plot (a) \(v_{O 1}-v_{O 2}\) versus \(v_{I}\) over the range \(0 \leq v_{I} \leq 4 \mathrm{~V}\) and (b) the current in \(R_{L}\) over the same input voltage range.

TYU 15.13 (a) Consider the bridge amplifier in Figure 15.46 with parameters R = R3 = 20 k2, R2 = 40 k2, R4 = 60 k2, and R = 500 2. Assume the op- amps are biased at 15 V and the peak output voltage of each op-amp is limited to +12 V. Determine (i) the voltage gain of each op-amp circuit, (ii) the average power that can be delivered to the load, and (iii) the peak amplitude of the input voltage VI. (b) From the results of part (a), change the values of R2 and R4 such that the same av- erage power is delivered to the load but the magnitude of the required input voltage is cut in half. What are the required amplifier gains? (Ans. (a) (i) Av1 = +3, Au2 = -3, (ii) PL = 0.576 W, (iii) v =4V; (b) R = 100 k2, R4 = 120 ks, Av = +6, A2 = -6)
