A Generic Current Mode Design for Multifunction Grounded Capacitor Filters Employing Log-Domain Technique

A generic design (GD) for realizing an nth order log-domain multifunction filter (MFF), which can yield four possible stable filter configurations, each offering simultaneously lowpass (LP), highpass (HP), and bandpass (BP) frequency responses, is presented. The features of these filters are very si...
