Step 1 of 4 9.076P Consider the effect of the load mismatch. The transistors and are perfectly matched. It follows that current, will divide equally between and Q2 and thus collector voltages are, Step 2 of 4 Calculate the differential output voltage, Step 3 of 4 The expression for differential gain including the emitter resistance is, Step 4 of 4 Calculate the expression for the input offset voltage. Substitute IRC for = 2 Rc = Therefore, the input offset voltage is
