Zusammenfassung:A novel technique is proposed to take advantage of system-level properties of applying negative feedback to an operational trans-hr) conductance amplifier to implement fully integrated large time constant integrators. Based on the proposed idea a first-order lowpass G sub( m)-C filter as an integrator with a cutoff frequency of 20 Hz has been designed, fabricated and tested. The experimental results are in close agreement with theoretical and simulation results.
