This paper presents an electronically tunable current-mode SIMO/MISO universal biquad filter using multi-output current controlled current conveyor transconductance amplifiers (MO-CCCCTAs). The proposed filter employs only two CCCCTAs and two grounded capacitors. The proposed configuration can be used as either single input multi-output (SIMO) or multi (three) input single output (MISO) current...

Characteristics of tunable wavelength pi’n/pin filters based on aSiC:H multilayered stacked cells are studied both experimental and theoretically. Results show that the device combines the demultiplexing operation with the simultaneous photodetection and self amplification of the signal. An algorithm to decode the multiplex signal is established. A capacitive active band-pass filter model is pr...

This paper presents a current-processing current-controlled universal biquad filter. The proposed filter employs only two current controlled current conveyor transconductance amplifiers (CCCCTAs) and two grounded capacitors. The proposed configuration can be used either as a single input three outputs (SITO) or as three inputs single output (TISO) filter. The circuit realizes all five different...

This paper presents two transadmittance mode universal filters having single voltage input and multiple current outputs. The filter employs three multiple output current controlled conveyors (MOCCCII) and two grounded capacitors. It can realize low pass, high pass, band pass, notch and all pass responses. As desired, the input voltage signal is inserted at high impedance input terminal and the ...

Abstract—This paper presents a voltage mode universal biquadratic filter with one input and five output terminals, realizing all the standard filter functions that are high pass, band pass, low pass, notch and all pass, without changing the circuit topology. The proposed circuit employs three plus-type differential difference current conveyors (DDCCs), three grounded resistors and two grounded ...

In this paper, two new electronically tunable filter configurations are proposed. The proposed filters operate current-mode (CM), voltage-mode (VM), transimpedance-mode (TIM) and transadmittance-mode (TAM). The first configuration realizes second-order VM band-pass and TAM high-pass filter characteristics from the same configuration. The second one realizes second-order TIM band-pass and CM low...

A new configuration for realizing currentmode multifunction filter using current feedback amplifiers for a single current input source is presented. The proposed current-mode circuit realizes simultaneously low pass, high pass and band pass filters where as notch and all-pass filter functions can also be realized by addition and/or subtraction of various filter functions without any substantial...

Abstract: This work contains a brief study of a new structure of a low-pass filter of N th order, operating in low frequencies. The low-pass filter is designed with CMOS technology and biased to work in weak inversion. The dimension of the lay-out of the circuit and very low power consumption enables this new structure be integrated in a single chip. The parameter n, dependent of the fabricatio...
