Abstract
A novel differentiator with differential inputs is described. It is characterized by a resistive input impedance and a single RC network which controls the differentiation action of the circuit. The differentiation of high-frequency noise is avoided by a transition to amplifier and integrator action at high frequencies. The common mode rejection ratio (CMRR) is more controllable in the new differentiator than in the traditional differential differentiator. Simulation and experimental results support the theoretical derivation
