Abstract :
A capacitor multiplier with large multiplication factor based on dual-output differential amplifiers is presented. The proposed circuit consists on multiple stages connected in series to provide a large multiplication factor, formed by transconductance differential amplifiers with dual outputs where one of the outputs provides a scaled current with respect to the other by a factor k. Simulation results in 0.5μm technology confirm the proposed operation.
