HW2_Q5: Assuming an ideal op-amp, find $V_o/V_i$ for the following circuit. HW2_Q6: For an ideal op-amp circuit where $\Delta R/R = 0.1$ and $V_1 = V_2 = V_c$, determine $V_o/V_c$.

Step 1
$V_o = \frac{100R}{R}(V_2 - V_1)$ Given $V_1 = V_2 = V_c$ and $\Delta R/R = 0.1$, so $\Delta R = 0.1R$. $V_o = \frac{100R}{R}(V_2 - V_1) = 100(V_2 - V_1)$ The gain of the non-inverting input is: $A_+ = \frac{100R + R + \Delta R}{R + \Delta R} = \frac{101R + Show more…

For the circuit in Fig. $\mathrm{P} 4.21.$ (a) find $V_{o}$ in terms of $V_{1}$ and $V_{2}.$ (b) If $V_{1}=2 \mathrm{V}$ and $V_{2}=6 \mathrm{V},$ find $V_{o.}$ (c) If the op-amp supplies are $\pm 12 \mathrm{V}$, and $V_{1}=4 \mathrm{V}$, what is the allowable range of $V_{2} ?$
Part 2: Now let's assume the op-amp is ideal with infinite internal gain. (4) Find the expression of the output voltage (v_{0}) as a function of the source signal (v_{s}). (5 marks)
