A bit-slice architecture for sigma-delta analog-to-digital converters

Efficient method based on Z-Transform techniques for coefficient calculation of sinc^N FIR filters

“…Suitable filters for high speed operation are required. Cascaded-integrator-comb (CIC) filters [1] and sinc N FIR filters [3,4] are among the well known solutions. The use of sinc N filters constituted of a cascade of N sinc filters, each of length M, demands the calculation of all of the impulse response coefficients.…”
