Pseudo-Differential High-Order Frequency Filter
MetadataShow full item record
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.
