Consider the bridge circuit in Figure P9.87. The resistor \(R_{T}\) is a thermistor with values of \(20 \mathrm{k} \Omega\) at \(T=300 \mathrm{~K}\) and \(21 \mathrm{k} \Omega\) at \(T=350 \mathrm{~K}\). Assume that the thermistor resistance is linear with temperature, and that the bridge is biased at \(V^{+}=10 \mathrm{~V}\). Design an amplifier system with an output of \(0 \mathrm{~V}\) at \(T=300 \mathrm{~K}\) and \(5 \mathrm{~V}\) at \(T=350 \mathrm{~K}\).
