Originální abstrakt

This paper deals with application of novel active block called multiple-output current follower transconductance amplifier (MO-CFTA) in multiple-loop structure of current mode active filter. The well-known transconductance amplifier (OTA) is modified in such a way that single-input multiple-output active block is obtained. Using this device in the suggested network structure allows us to achieve low pass (LP), high pass (HP), band pass (BP) and band reject (BR) filter. The effects of the parasitic properties of the active devices as well as biquad sensitivities are briefly discussed. The possibility of electronic tuning of the main parameters of the individual filter configuration is verified.
