Infineon Technologies AG hat auf der ISSCC 2004 (14. bis 19. Februar in San Francisco) in mehreren Beiträgen innovative CMOS-basierte Schaltungen für die drahtlose und drahtgebundene Kommunikation gezeigt. Die Designs markieren wichtige Meilensteine auf dem Weg zur nächsten Generation der High-Speed-Kommunikation mit bisher unerreichten Leistungsmerkmalen. Dazu gehören ein vierkanaliges ADSL2+ Analog Front End mit sehr geringer Verlustleistung, ein leistungsoptimierter Delta-Sigma-Modulator für ADSL, die erste vollintegierte 13-GHz-PLL-Schaltung in CMOS und ein schneller 10-bit-AD-Wandler mit neuen Algorithmen für Wireless-LAN-Anwendungen.
Vierkanaliges Analog Front End für ADSL2+ benötigt nur 75 mW je Kanal
