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.
