The bridge circuit in Figure P11.27 is a temperature transducer in which the resistor RA is a thermistor (a resistor whose resistance varies with temperature). The value of δ varies over the range of −0.01 ≤ δ ≤ 0.01 as temperature varies over a particular range. Assume the value of R = 40kΩ. The bridge circuit is to be connected to the diff-amp in Figure 11.2. The diff-amp circuit parameters are V+ = 5 V, V− = −5 V, IQ = 0.2 mA, and RC = 15kΩ. The transistor parameters are β = 120, VBE(on) = 0.7 V, and VA = ∞. Terminal A of the bridge circuit is connected to the base of Q1 and terminal B is connected to the base of Q2 Determine the range of output voltage vo2 as δ changes. [Hint: Make a Thevenin equivalent circuit at terminals A and B of the bridge circuit.]
