VLSI implementation of a second-order digital filter
S. Sunder, F. El-Guibaly, A. Antoniou · Canadian Journal of Electrical and Computer Engineering · 1994
The implementation of a second-order digital filter is discussed. A novel multiplier, by means of which an inner product operation is performed without the use of an accumulator, is used as a component in the second-order filter to achieve significantly reduced area and noise. In this multiplier, maximum use is made of all the cells comprising the multiplier.
