This paper presents a new voltage-mode multiple-input multiple-output (MIMO) multifunction filter using five single-ended operational transconductance amplifiers (OTAs), two capacitors and one resistor. The proposed filter can provides low-pass, band-pass, high-pass, band-stop and all-pass voltage responses by appropriately connecting the input and output terminals. The natural frequency and the quality...
This paper presents a new versatile high input impedance voltage-mode universal filter with multiple-input multiple-output (MIMO) based on single-ended operational transconductance amplifiers (OTAs) and grounded capacitors. The proposed circuit can work as a two-input four-output filter and a three-input single-output filter without changing the circuit topology. The natural frequency (ωo) and the...
An OTA-C current-mode universal filter with independent tunable-Q realized by band-reject function is proposed. The proposed circuit employs OTAs and grounded capacitors. The parameter QP can be tuned independently from omegaP. However, the other different kinds filter function as low-pass, high-pass, band-pass and band-reject response can be also obtained without changing circuit topology. The parameters...
