Abstract

In this Letter, a general compensation method for finite parasitic output impedance of G_m in G_m-C lossless integrator is discussed. The use of a G_m-simulated negative resistor in series with an integrating capacitor in a lossless integrator is shown to minimise the effects of the finite output impedance of G_m-cell. The proposed method is employed in a second-order G_m-C notch filter to improve the stop-band response of the filter.
