High-speed digitizers operating at sampling rates higher than 10GS/s require low-pass anti-aliasing filters in the multi-GHz range. Asynchronous Time-Interleaved (ATI) also need before digitization, and additional requirements on their design are set by this specific application. In integrated solutions, inductor-less important for minimizing chip area footprint. paper, we present of a 6th...

This paper presents a new mixed-mode (including voltage, current, transadmittance, and transimpedance modes) biquad filter using only two differential voltage current conveyors (DVCCs), two grounded capacitors and three grounded resistors, which are the least number of active components and the minimum number of grounded passive components necessary for realizing current-mode (with high output ...

This paper presents an electronically tunable current-mode biquadratic filter constructing with four Zcopy current follower transconductance amplifiers (ZCCFTAs) and only two grounded capacitors. The presented filter can realize all the five standard biquadratic functions simultaneously without requiring any component matching conditions and connecting any relevant output currents. The circuit ...

The second order Sallen-Key low-pass filter structures have one disadvantage in the voltage and current mode, it is a decreasing of the attenuation in the stopband. This fact is caused by losses of the amplification factor of active elements at high frequencies. Some solutions of this problem had been already published for circuits working in the voltage mode. This article presents one of the p...

In this paper, a design procedure for the realization of all current-mode biquadratic transfer functions is presented. The synthesis technique is deduced from a signal flow graph representation using current follower transconductance amplifiers (CFTAs). The proposed configuration has single low-impedance input and five high-impedance outputs, and comprises three CFTAs and two grounded capacitor...

A simple current-reversible chaotic jerk circuit is proposed and particularly demonstrates the use of inherently tanh(x) nonlinearity of a single opamp for a chaotic jerk circuit. No additionally nonlinear devices are required. Bifurcation is electronically tunable through a current source in a reversible direction. The largest Lyapunov exponent of either direction forms mirror images, whereas ...

A technique for designing high-linearity continuoustime integrated filters for low frequency applications using transconductance network is presented. With this technique, an area-efficient transconductance network is used to replace the large resistors in low-frequency integrator-based continuous-time filters. The key challenge with this technique is in determining and realizing the appropriat...

The recent loudness measurement recommendations by the ITU and the EBU have gained widespread recognition in the broadcast community. The material it deals with is usually full-range mastered audio content, and its applicability to multitrack material is not yet clear. In the present work we investigate how well the evaluated perception of single track loudness agrees with the measured value as...
