“…This is advantageous for applications such active filters and oscillators. The EX-CCCII can be used for applications such as oscillators [19][20][21][22][23], instrumentation amplifiers [24,25], immittance simulators [26], precision rectifiers [27], first-order filters [28][29][30], and universal filters [31][32][33][34]. This work focuses on the EX-CCCII based universal filter.…”

This paper presents a novel multiple-input and multiple-output current-mode universal analog filter with electronic tuning capability. The proposed circuit uses a single second-generation current-controlled current conveyor with extra-X terminals (EX-CCCII) and two grounded capacitors. The filter can offer five standard filtering functions, namely low-pass, high-pass, band-pass, band-stop, all-pass responses, in the same circuit without changing the internal configuration of the filter by selecting appropriate input and output signals. To obtain the five standard filtering functions, inverted input signal and input matching conditions are absent. The natural frequency of all filter responses can be electronically controlled. The proposed circuit was simulated by SPICE using 0.18 μm CMOS process from Taiwan Semiconductor Manufacturing Company (TSMC). The results of experiments using the integrated circuit operational amplifier AD844 confirm the functionality of the new filter.
