Abstract

A log-domain differentiator circuit, constructed using an appropriate input stage and a multiplier block, is proposed in this Letter. The input stage compresses the voltage at the capacitor's nodes and simultaneously produces a replica of the current that flows through the capacitor. The multiplier block realizes the desired output current. The analysis of the proposed circuit has been verified through simulation results.
