Abstract
Rake receiving is a crucial technique in spread spectrum system. Typical rake receivers, implemented all-digitally, entail considerable power consumption. Though generally regarded as a promising low power solution, analog rake receivers have not been widely adopted because of formidable design complexity in integrating the overall analog and digital systems. In this paper, we present a practical scheme to realize a digitally-controlled mixed-signal rake receiver with both software and hardware simulation results demonstrating the efficiency of the proposed system. Synthesis and SPICE simulations using 0.18/spl mu/m CMOS technology show that the power consumption is less than 2.5 mW while operating at 16 MHz clock rate at 1.5 V supply voltage.
