In recent years, continuous research efforts have been concentrating in increasing ΣΔ modulators operating frequency, while still reducing their power consumption. Indeed, when the ΣΔ modulator figure of merit (FoM) is less than 1 pJ/conversion, the decimation filter power consumption becomes a critical parameter. This paper presents a low power sin3 FIR filter for ΣΔ modulators. The proposed filter implements a decimation by 4, operating at 64 MHz and consumes only 0.1 pJ/sample processed. The…
