The benefits of adaptive power reconfigurability in WPAN receivers are investigated. The analysis is based on a direct-conversion IEEE 802.15.4 receiver and is focused on the analog baseband block. High-level power models are built for the baseband filter and the ADC which are, then, optimized for minimum total power dissipation to decide on the reconfiguration strategy. The optimum is reached with...
The impulse radio-ultra wide band (IR-UWB) signalling format has been an attractive mode for wireless communication in wireless sensor node system. The super-regenerative principle can be used for impulse reception for its inherent advantages. The oscillator is the main building block in a super-regenerative based impulse reception system. It is necessary for the oscillator to be tuned to the carrier...
