Wave digital filters: Theory and practice
TL;DR: Wave digital filters (WDFs) as discussed by the authors are modeled after classical filters, preferably in lattice or ladder configurations or generalizations thereof, and have very good properties concerning coefficient accuracy requirements, dynamic range, and especially all aspects of stability under finite-arithmetic conditions.
Journal ArticleDOI
Low-sensitivity digital ladder filters
TL;DR: In this paper, a class of low-sensitivity digital ladder filters may be realized in the voltage-current domain by direct analogy with the continuous resistively terminated LC ladder filter by using transformations that correspond to LC elements that exhibit finite Cube factors.
Journal ArticleDOI
Realization of a class of analog signal processing / signal generation circuits : Novel configurations using current feedback op-amps
TL;DR: In this paper, the current feedback op-amps (CFOA) or transimpedance op-amp (TOP-AMP) are used as 4-terminal building blocks for analog signal processing and signal generation functions, including impedance converters/ inverters, voltage-controlled impedances (both grounded and floating), active filters (both current mode and voltage mode) and single-resistance-controlled/voltage-controlled sinusoidal oscillators.
Journal ArticleDOI
High-quality factor asymmetric-slope band-pass filters: A fractional-order capacitor approach
TL;DR: New techniques for implementing continuous-time second-order band-pass filters with high-quality factors and asymmetric slopes with non-integer-order Laplacian operator sα are presented.
Journal ArticleDOI
Integration of analog filters in a bipolar process
TL;DR: In this paper, the integration of electronic transconductors and capacitors has been used to simulate inductor capacitors for analog low-pass filters, which are on-chip compatible with analog and digital parts.

RC-active synthesis using positive-immittance convertors
TL;DR: In this paper, positive-immittance convertors (p.i.c.s) with a purely reactive conversion ratio are used to simulate inductors in LCnetworks, which results in simulated inductors whose magnitudes are controlled by resistor networks.
Journal ArticleDOI
Practical Realization of a Gyrator Circuit and RC-Gyrator Filters
TL;DR: In this paper, a gyrator circuit with only three transistors was designed by providing an active feedback path such that the circuit behaves like a two-way feedback system with transfer immittance parameters that are equal in magnitude and opposite in phase.
Journal ArticleDOI
Frequency selectivity using positive impedance converter-type networks
TL;DR: In this article, it is shown that positive impedance converter-type networks may be used to realize a driving point impedance that is ideally a frequency dependent negative resistor, which can be used for new types of inductorless selective networks.
Journal ArticleDOI
Gyrator-flotation circuit
TL;DR: In this paper, an alternative circuit is proposed which avoids this matching problem and can be used with most existing gyrators, but it requires very close matching of the gyrator.
Journal ArticleDOI
Direct-coupled gyrators with floating ports
TL;DR: An integratable high-performance direct-coupled gyrator circuit which is capable of being used in the simulation of floating inductors for lowpass filters is presented, and some of the peculiarities of practical floating gyrators are discussed as discussed by the authors.
