Question:

The circuit shown in Figure P5.41 is sometimes used as a thermometer. Assume the transistors \(Q_{1}\) and \(Q_{2}\) in the circuit are identical. Writing the emitter currents in the form \(I_{E}=I_{E O} \exp \left(V_{B E} / V_{T}\right)\), derive the expression for the output voltage \(V_{O}\) as a function of temperature \(T\).
