Abstract :
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 frequency of the received pulse for achieving maximum sensitivity. In this paper, a multi-band tuning circuitry based on the frequency synthesizer architecture is shown. The oscillator can be tuned to either 3.494 GHz or 3.993 GHz. The circuit is implemented in a CMOS 0.18 mum technology and consumes 8 mA current at 1.5 V supply voltage.
