Original Abstract

This paper presents simple electronically reconfigurable and reconnection-less filtering applications based on useful modification of current differencing unit (CDU). Modified CDU improves its controllable features and bring some other advantages. Three examples of first-order filtering structure in voltage- and current-mode were studied and compared. The last presented solution providing all-pass, inverting high-pass and low-pass (and theoretically also direct transfer) responses was investigated by PSpice simulations using complex behavioral model of the modified CDU, based on commercially available devices. It confirmed theoretically expected behavior.

Tento článek prezentuje jednoduché elektronicky rekonfigurovatelné (bez fyzického přepojení) filtrační aplikace založené na užitečné modifikaci proudové diferenční jednotky (CDU). Modifikovaná CDU vylepšuje svoje řiditelné vlastnosti a přináší jisté další výhody. Tři příklady filtračních struktur prvního řádu v napěťovém a proudovém módu jsou studovány a porovnány. Poslední řešení, poskytující přenos typu fázovací článek, invertující horní propust a dolní propust (a teoreticky také přímý přenos - propojení), bylo zkoumáno simulacemi v PSpice využívajícími komplexní behaviorální model modifikované CDU založený na komerčně dostupných prvcích. To potvrdilo teoreticky očekávané chování.
