Abstract—This letter describes a direct-sequence spread-spectrum wD22@uM#]  
superregenerative receiver operating at 2.4 GHz and using O4]Ss}ol  
a simple PN code synchronization loop. The receiver minimizes X
xB*lX  
overall complexity by using a single signal processing path for data 0b?9LFd  
detection and PN code synchronization. An analytical description O JvEq@  
of the loop dynamics is presented, and the conditions for optimum ;=_<\2  
performance are examined. Experimental results confirm the receiver’s wW6?.}2zU  
ability to perform acquisition and tracking, achieving a KD-0NO=oL  
sensitivity of 97 dBm and an input dynamic range of 45 dB. The bxrByu~|1  
RF part consumes 0.9 mA at a supply voltage of .. l"CHI*
