Abstract :
A temporal moving-average (TMA) filter that has a high-order sinc-type frequency response is proposed. The proposed TMA filter has a smaller size and higher gain than conventional filters. To verify the proposed architecture, a third-order TMA filter is designed using TSMC 0.13 μm CMOS technology and is compared with a theoretical analysis. Circuit level simulations show good agreement with the theoretical analysis.
