Problem 7.3 (20 points) Consider an ideal op-amp network depicted in Figure P7.3. (a) What are the terminal voltages (v−, v+) and currents (i−, i+) of the inverting and noninverting terminals, respectively. (b) Express the output voltage V0 in terms of the resistors and the input voltages Vs1, Vs2. Does it depend on the load resistor RF? Then evaluate V0. Figure P7.3 Vs1 = 6 V, Vs2 = 2 V, Rs = 1 kΩ, RF = 4 kΩ, RL = 2 kΩ

(i_{-}, i_{+})

of the inverting and noninverting terminals, respectively. (b) Express the output voltage

V_{0}

in terms of the resistors and the input voltages

V_{s 1}, V_{s 2}

. Does it depend on the load resistor

R_{F}

? Then evaluate

V_{0}

. Figure P7.3

V_{s 1} = 6 V, V_{s 2} = 2 V, R_{s} = 1 k Ω, R_{F} = 4 k Ω, R_{L} = 2 k Ω
