Multifunctional current-mode filter with dual-parameter control of the pole frequency
Advances in Electrical and Computer Engineering, 2016 This paper presents a multifunctional current-mode filter with dual-parameter control of the pole frequency. The filter is of the second order, of single-input triple-output (SITO) type and a required type of the response (low pass, inverting band pass,
