Reliable real-time sensing plays a vital role in ensuring the reliability and safety of industrial cyberphysical systems (CPSs) such as wireless sensor and actuator networks. For many reasons, such as harsh industrial environments, fault-prone sensors, or malicious attacks, sensor readings may be abnormal or faulty. This could lead to serious system performance degradation or even catastrophic failure...
A low-power transceiver for 802.11n in 65 nm CMOS technology is presented. It supports 2times2 MIMO to satisfy the requirement of the draft 802.11n standard. In receiver chain it shows 5.3 dB low noise figure. In transmit chain an on-chip PA driver delivers 9 dBm output P1dB. -20 to 100degC operation temperature is achieved. A SigmaDelta fractional-N synthesizer is used to support variable reference...
