A 1V RF SoC with an 863-to-928MHz 400kb/s radio and a 32b Dual-MAC DSP core for Wireless Sensor and Body Networks

Abstract

A 150¿A/MHz DSP with two MAC/cycle instructions is integrated with a configurable 863-to-928MHz RF transceiver that yields 3.5mW in continuous reception, 2¿C per channel sampling and 40mW for 10dBm output. The SoC includes voltage converters that allow 1.0-to-1.8V or 2.7-to-3.6V primary voltage supplies. In sleep mode, it consumes 1¿A with a 32kHz crystal-based RTC running.
