Abstract

This paper presents a novel method for Quadrature Direct Digital Frequency Synthesizer with super high compression ratio which is based on the Taylor expansions. For a 32bit-QDDFS system, 16Gbytes' data can be compressed to less then 2KBytes while the SNR can get to 184dB, so it can be realized in one CMOS chip or FPGA. The traditional DDFS architecture is changed in which accumulator is replaced by Phase Tipster in this system. By this excellent method, super high frequency resolution is achieved. At last, a simple configuration of this system is given.
