摘要：The traditional DDFS based on a look up table needs a large sized ROM and it is more complex. This paper deals with a novel ROM-less architecture based on the approximation of Euler’s Infinite series. It has advantages of low complexity, low computational delay, and high spectral purity. The proposed DDFS has a high SFDR (spurious free dynamic range) when compared with [1] and the value is as good as 72.3dBc.
