Summary
The following paper presents a 2.1 GHz transceiver, which makes use of BAW resonators to replace the external quartz crystal and the external band select filter. It has been fabricated in a 130 nm CMOS process and has a power consumption of 5 mA. To derive the specifications for the transceiver the requirements of a TPMS have been taken into consideration.
Zusammenfassung
Der folgende Artikel stellt einen 2,1-GHz-Transceiver vor, der anstelle einer externen Quarzreferenz und eines externen Hochfrequenzfilters BAW-Resonatoren einsetzt. Der Chip wurde in einem 130-nm-CMOS-Prozess gefertigt und hat einen Stromverbrauch von 5 mA. Um die Spezifikationen abzuleiten, wurden die Anforderungen an ein TPMS (Reifendrucküberwachungssystem) betrachtet.
