Tunable Universal Fully-Differential Filter With Operational Transresistance Amplifier
MetadataShow full item record
The new single-ended (S-E) second order frequency filter providing transfer function of Low Pass (LP), High Pass (HP), Band Pass (BP), Band Stop (BS) and All Pass (AP) is presented in this paper. The cut-off frequency is tunable up to 3 MHz. Also the fully-differential (F-D) version of the filter is presented and so is the transformation method which is in this case the Signal Flow Graph (SFG). The design filter can be implemented with discretive active devices or as an Integrated Circuit (IC). The features of both S-E and F-D filters are verified using PSpice simulations comparing ideal and behavioral models of the active devices.
