Abstract :
A design procedure is presented for a hardware efficient FIR compensation filter as a component in a delta sigma modulator analog to digital converter using cascaded sine low pass filters. The combination of the sine low pass filters and the hardware efficient FIR compensation filter results in a 21% saving in hardware (chip area) compared to a single FIR low pass filter
