Universal voltage-mode filter with four inputs and one output using two CCII s

First, Second and Higher Order Filter Design Using Current Conveyors

“…and BPF can also be obtained with 6.15 VM universal filter using two CCII+ proposed by Chang and Tu [13] If CCIIs of Fig. 6.16b are exchanged, another universal filter can also be achieved.…”

ICCII-Based Voltage-Mode Filter with Single Input and Six Outputs Employing Grounded Capacitors

“…As a result, a negative-type inverting second-generation current conveyor (ICCII-) has been proposed [1]. Quite a large number of studies have been devoted to the second-order voltage-mode analog filter realizations [2]- [5], [8]- [13]. The filters in [3], [5], [8], [10]- [13] can realize only one filter response at a time.…”

“…Quite a large number of studies have been devoted to the second-order voltage-mode analog filter realizations [2]- [5], [8]- [13]. The filters in [3], [5], [8], [10]- [13] can realize only one filter response at a time. The filter in [2] can simultaneously realize lowpass and bandpass and notch responses, and the filters of [9] and [4] can simultaneously realize lowpass, bandpass, and highpass responses.…”

“…Contrary to the filters reported in [2]- [5], [8]- [13], we propose a new filter with the following advantageous features:…”

Synthesis of Cascadable DDCC-Based Universal Filter Using NAM

“…The design of biquadratic voltage-mode active filters with high-input impedance has received much interest since they can be directly cascaded to implement higher order filters without the use of additional buffer circuits [1]. Many voltage-mode universal biquadratic filters using current conveyors with multi-input/multi-output were proposed in the literature [2][3][4][5][6][7][8][9][10].…”
