Abstract

This paper reports a multitude of HSPICE simulation results corresponding to high-order (fifth, sixth and tenth) differential class-A log-domain lowpass and bandpass ladder filter topologies. The designs are elliptically approximated and were obtained by means of an appropriately extended version of the XFILTER filter compiler. The nondesirable effect of the BJT finite beta is shown; circuit modifications mitigating-to a certain extent-the device nonideality-induced impact are also reported
