Compensation of Gm-C lossless integrator for finite output resistance
In this Letter, a general compensation method for finite parasitic output impedance of G in G -C lossless integrator is discussed. The use of a G -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 -cell. The proposed method is employed in a second-order G -C notch filter to improve the stop-band response of the filter. m m m m m
