This paper describes an ultra-low-power RF transceiver implemented as part of a system-on-chip. The transceiver operates in the 868/915 MHz frequency band using binary FSK modulation at a 45 kbit/s data rate. It achieves -89 dBm receiver sensitivity and -6 dBm transmitter output power while consuming 1.6 mA and 1.8 mA, respectively, from a 1.2 to 1.5 V supply. It is fabricated in 0.13 mum CMOS occupying...
G2 microsystems of Campbell, California, USA, released in 2007 the first ever ultra-low power Wi-Fi System on a Chip (SoC) named G2C501. This SoC includes a 32-bit CPU, crypto accelerator, real-time clock and a versatile sensor interface that can serve as a standalone host subsystem. The G2C501 goes beyond todaypsilas basic radio frequency identification (RFID) technology to offer intelligent tracking...
