Gyrator video filter IC with automatic tuning
TL;DR: In this article, a single-chip gyrator filter for separating the components of the video signal in a TV receiver is described which is suitable for mass production in a standard bipolar process (f/SUB T//spl ap/400 MHz).
Journal ArticleDOI
Noise in Gm-C filters
TL;DR: Topology-independent bounds for the signal-to-noise ratio (SNR) are derived and Expressions for certain products of noise with frequently used quantities are derived, and are shown to be invariant under certain actions, which are sometimes taken in order to improve the SNR.

New Active Filter synthesis based on Scattering Parameters
H. Wupper,K. Meerkotter +1 more
TL;DR: In this paper, a method for the synthesis of active filters based on processing of wave quantities is presented and some experimental results confirm the feasibility of the principle and possibilities for practical implementation are shown.
Journal ArticleDOI
Noise and Group Delay in Active Filters
TL;DR: The output noise spectrum and the group delay of active filters are related, and this relationship allows for quick noise estimates, and gives insight into the noise behavior of filters.
Journal ArticleDOI
General results for resistive noise in active RC and MOSFET-C filters
TL;DR: In this paper, the relationship between sensitivity and noise is considered and a bound for the product of resistive power dissipation and noise power spectral density is derived for active RC and MOSFET-C filters.

Tellegen's theorem and electrical networks
TL;DR: In this paper, the authors present a collection of theorems that can be proved from Tellegen's theorem for nonlinear and time-varying networks, including nonlinear, time-invariant or time-variant, reciprocal or non-reciprocal, passive or active, single-valued or multiple-valued, hysteretic or nonhysteretic, and non-hybrid.

Inductorless bandpass filters
H.J. Orchard,D.F. Sheahan +1 more
TL;DR: The technique of designing inductorless filters by replacing the inductors in conventional LC filters with gyrators and capacitors is considered for the special case of the high-quality channel bandpass filters used in multiplex telephony.
Journal ArticleDOI
On the connection between multiplier word length limitation and roundoff noise in digital filters
TL;DR: In this article, it was shown that roundoff noise can be interpreted as coefficient fluctuation, and any design method requiring fewer digits for the multipliers makes it possible to increase the signal word lengths without an increase in overall complexity.
Journal ArticleDOI
Roundoff noise and attenuation sensitivity in digital filters with fixed-point arithmetic
TL;DR: In this paper, a general expression was established which relates the output roundoff noise generated by a fixed-point multiplier in a digital filter to the sensitivity of the filter attenuation with respect to the corresponding multiplier coefficient.
Journal ArticleDOI
Relations Between Reactive Energy and Group Delay in Lumped-Constant Networks
G. Kishi,K. Nakazawa +1 more
TL;DR: In this article, the authors proved that a lumped-constant network is supposed to be excited by means of one or more sinusoidal sources with the same frequency, and obtained a multiterminal network including only reactive elements.
