Adjustable Fractional-Order High-Pass Filter with Transconductance Amplifiers
MetadataПоказать полную информацию
This paper deals with proposal of a fractional-order high-pass filter with electronically tunable pole frequency and its order. The filter is designed using operational transconductance amplifiers (OTAs), current follower (CF) and adjustable current amplifiers (ACAs). Function of proposed filter was verified using simulations in PSpice simulator. The circuit features were verified in simulations for three values of order of the filter and four values of cut-off frequency. In this paper, possibility to tune the cut-off frequency using the values of passive components is also mentioned.
