Automatic generation of CMOS continuous-time elliptic filters
W.R. Daasch, Martine Wedlake, Rolf Schaumann · Electronics Letters · 1992
A procedure for the generation of CMOS, contnuous-time, high-frequency gm-C filters with finite transmission zeros is presented. A third-order elliptic filter with 0.5 dB equiripple passband, 15 MHz cutoff frequency and −23dB attenuation in the stopband is given as an example. The automatic generation method can be generalised to arbitrary high-order prototypes and higher-frequency filters derived from LC ladders.
