—A long-range UHF RF identification (RFID) sensor has been designed using a 0.35-µm CMOS standard process. The power-optimized tag, combined with the ultralow-power temperature sensor, allows an ID and a temperature reading range of 2 m from a 2-W effective radiated power output power reader. The temperature sensor is based on a ring oscillator, where the(More)
This paper presents the design and implementation of a 2K/4K/8K multiple mode FFT core for DVB-T/DVB-H receivers. The proposed core is based on a pipeline radix-2 2 SDF architecture. The necessary changes in the radix-2 2 SDF architecture to achieve an efficient FFT implementation are detailed. Quantization effects and timing design parameters are analyzed(More)
