Synthesis Of Electronically Reconfigurable 3rd-Order Flf-Os Filter In Singleended And Fully-Diferential Design
Theumer, Radek
This paper deals with a proposal of 3rd-order single-ended and fully-differential frequency filters based on the follow-the-leader-feedback topology with the output summation (FLF-OS) working in the current mode. The main feature of both of these filtering structures is an ability of the electronic reconfiguration of their transfer functions. Active elements used for the filter design are implemented by transconductance amplifiers, current amplifiers and current followers. Simulation results of available transfer functions, their tunability and comparison of both circuits are presented.
Pseudo-Differential High-Order Frequency Filter
Sládok, Ondřej
This article describes a pseudo-differential third-order frequency filter operating in voltage mode, using four differential difference current conveyors (DDCCs), and six passive elements. The circuit has a high input impedance, low active and passive sensitivity and high common-mode rejection ratio (CMRR). The proposed structure is able to realize one type of frequency responses low pass. Non-ideal analysis has been performed by considering the real parasitic parameters of the active elements. Optimization was made with a view to greatly influence low pass filter attenuation.
