Abstract :
This paper presents an ASIC implementation of a WCDMA Rake receiver. The implementation is based on a FlexRake architecture that shares resources between multipath components and uses parallelism for multiple code channels. This approach facilitates the multipath allocation and improves the receiver modularity. The architecture was implemented using register-transfer-level VHDL description and logic synthesis with standard cells. Synthesis for 0.35 μm technology resulted in 0.894 mm2 area and 3.63 mW power consumption at 2.7 V.
