Performance Analysis of Sigma-delta ADC with Fractional Sample Rate Conversion
Akira Tanaka, Mamiko Inamori, Yukitoshi Sanada (Keio Univ.) SR2010-40
Abstract (in Japanese) (See Japanese page) 
(in English) This work presents a sigma-delta analog-to-digital converter (ADC) with Fractional Sample Rate Con-
version (SRC). Our previous report proposed a fractional sample rate conversion by direct insertion/deletion method.
However, the method requires a lowpass lter be placed after the sigma-delta modulator. The proposed method
in this report realizes SRC and low speed lowpass lter by decimating the sigma-delta modulated signal before
a FIR lowpass lter. Simulation results show that the current proposed method achieves similar performance as
conventional methods but at a lower adder clock speed.
