A fully integrated transceiver suitable for low-data-rate wireless telemetry and sensor networks operating in the license-free ISM frequency bands at 433, 868, or 915 MHz implemented in 0.25-/spl mu/m CMOS is presented. G/FSK, ASK, and OOK modulation formats are supported at data rates from 0.3 to 200 kb/s. The transceiver's analog building blocks include a(More)
A fully integrated ISM-band transceiver in 0.25/spl mu/m CMOS for low data-rate wireless networks consumes 17mA from a 3V supply in FIX mode. At +10dBm output power, the part consumes 24mA. G/FSK and OOK/ASK modulation formats are supported at data rates from 0.3-128kb/s in the 433/868/915MHz ISM bands.
The IC presented in this paper is a highly integrated low-power RF transceiver for wireless sensor networks (WSN) compliant with the IEEE 802.15.4 2.4GHz WPAN standard. It contains a radio controller with sleep timer and can perform higher-level MAC functions such as beacon detection and network timing synchronisation autonomously, thereby enabling(More)
This article describes the design considerations for low-power short-range radio transceivers with a focus on the 2.4 GHz PHY layer defined as part of the IEEE 802.15.4 standard. The specification requirements for IEEE 802.15.4-compliant transceivers, and the design challenges and practical implementation of a highly-integrated low-power 2.4 GHz transceiver(More)
