| Abstract(in English) | This work presents a sigma-delta analog-to-digital converter (ADC) with Fractional Sample Rate Conversion (SRC). Our previous report proposed a fractional sample rate conversion by direct insertion/deletion method. However, the method requires a lowpass filter be placed after the sigma-delta modulator. The proposed method in this report realizes SRC and low speed lowpass filter by decimating the sigma-delta modulated signal before a FIR lowpass filter. Simulation results show that the current proposed method achieves similar performance as conventional methods but at a lower adder clock speed. |
