Journal ArticleDOI
Passive CCD resonator filters
TL;DR: Novel passive recursive CCD bandpass filters have been realized using standard two-level-polysilicon gate NMOS technology to achieve low power consumption and an extremely stable center frequency and a bandwidth independently controlled by a capacitance ratio.
Proceedings ArticleDOI
Passive Recursive CCD Resonators
TL;DR: In this article, the basic resonator consisting of one closed CCD loop as well as an extension -the double resonator -was described, which is useful to build extremely sharp integrated filters.
Proceedings ArticleDOI
A CCD wave filter with low sensitivity for FDM telecommunication systems
TL;DR: A monolithic Chebyshev CCD wave filter with a center frequency of f o = 50kHz and a relative bandwidth of 4.2, 5dB insertion loss and 60dB stopband attentuation was described in this article.
Patent
Als Schalter-Kondensator-(SC)-Filter ausgebildete Modulatorschaltung
TL;DR: Angegeben wird eine Modulatorschaltung, die unmittelbar mit einem Schalter-Kondensator-Filter verknupft ist.
Journal ArticleDOI
Bandpässe mit CCD-Resonatoren
TL;DR: In this paper, two band-pass filters with novel CCD resonators were realized in double-polysilicon-gate NMOS technology, and experimental results were discussed for a Chebyshev bandpass with a relative 3 dB-bandwidth of 3.1 %.
