This paper presents a single current controlled current conveyor trans-conductance amplifier (CCCCTA)based multi-input single output (MISO) voltage-mode universal biquad filter. The proposed filter employs only single CCCCTA, two capacitors and one permanently grounded resistor. The proposed filter realizes all the standard filter functions i.e. low pass (LP), band pass (BP) and high pass (HP),...

This paper presents an efficient method for the design of two-channel quadrature mirror filter (QMF) bank by polyphase representation of low-pass prototype filter and power optimization method for minimization of an objective function. The objective function is formulated as linear combination of pass-band error and stop-band residual energy of the low-pass analysis filter of the filter bank. O...

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. According to recent literature, the most appropriate preprocessing to improve P300 detection is still unknown or at least there is no consensus about it. Research papers refer to different low-pass filters, high-pass filters, baseline, subsampling or feature selection. In this paper, using a database with 23 healthy subjects we compare the effect on the letter accuracy (single-trial d...

Filter design specifications can be manifest in all manner of necessity, whether they are high-pass, low-pass, band-pass, or stop-band filters. In addition, the parameters for such filters are defined for a very specific application. A design for a lowpass filter with a pass-band of 2k Hz and a stop-band of 4k will be discussed. The further properties of the filter are to allow for a 48 dB drop...

Digital filter plays an important role in digital signal processing applications. Digital filter can also be applied in speech processing applications, such as speech filtering, speech enhancement, noise reduction and automatic speech recognition among others. In this paper Matlab program is used to implement a low-pass FIR filter using adjustable window function based on Hamming window. In som...

This paper deals with the design of low-power, highperformance, continuous-time filters. The proposed OTA architecture employs current-reuse differential difference amplifiers in order to produce more power efficient Gm-C filter solutions. To demonstrate this, a 6th order low-pass Butterworth filter was designed in 0.18 μm CMOS achieving a 65-MHz -3-dB frequency, an in-band input-referred third...

A current differencing transconductance amplifier (CDTA)-based multiple-input single-output (MISO) currentmode universal filter and a quadrature oscillator (QO) are presented in this paper. The same circuit is used in the filter and oscillator, which only consists of 2 CDTAs and 2 capacitors. The universal filter can realize low-pass, high-pass, band-pass, band-stop, and all-pass biquad filter ...

This paper presents a novel CMOS low-voltage and low-power positive second-generation current conveyor (CCII+ ). The proposed CCII+ uses two n-channel differential pairs instead of the complementary differential pairs; i.e. (n-channel and p-channel), to realize the input stage. This solution allows almost a rail-to-rail input and output operation; also it reduces the number of current mirrors n...
