Abstract
A novel method for quadrature direct digital frequency synthesizer with ten millions compression ratio, which is based on the Taylor expansions of sine and cosine, is firstly put forward. The traditional DDFS architecture is changed while accumulator is replaced by phase tipster in this system. Through this excellent method, super high frequency resolution is achieved. At last, a simple configuration of this system is presented
