Original Abstract

In the article the new active elements, the Current Follower Transconductance Amplifier (CFTA) and Current Mirror and Inverter (CMI) for the realization of the current-mode analog blocks, are presented. The proposed internal bipolar structure of the CFTA is presented. The usage of this active element is shown on the design of the universal SIMO (single-input-multi-output) type frequency filter working in the current-mode. The frequency filter emloying the CFTA and CMI elements has been synthesized using the signal-flow graphs. The filter enables realizing not only the basic functions such as the low- (LP), band- (BP) and high-pass (HP) but also the band-stop (BS) and all-pass (AP) responses. The properties of the filter proposed were verified by sensitivity and AC analyses in the PSPICE program.
