Abstract
A new high-speed direct digital frequency synthesizer using a low power pipelined parallel accumulator is proposed. The proposed pipelined parallel accumulator uses both pipelining and paralleling techniques to increase speed and to reduce power consumption. The 2-pipelined 2-parallel accumulator only consumes 66% and 69% power of the 4-pipelined accumulator and the 4-parallel accumulator respectively with the same throughput. The proposed accumulator can achieve higher throughput with smaller area and less power consumption in lower clock frequency. All circuit simulations and implementations are based on a 0.35um CMOS process with VCC = 3.3V.
