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.
