Question
(a) You have been given two logarithmic amplifiers which have exact matched pairs of transistors and resistors. The input voltages in the two amplifiers are V1 and V2 respectively. i) Design a circuitry system using these log amplifiers and any other opamp/opamps required to eliminate the reverse saturation current of the |log amplifiers at the final output which is amplified form of log (V1/V2). Draw diagram as required. ii) Show all the calculations as required.
