IEEE Pacific Rim Conference on Communications, Computers and Signal Processing June 1st - 2nd, 1989 VLSI IMPLEMENTATION OF ADAPTIVE BIT/SERIAL I IR FILTF':.
Rajeev Badyal, Sayfe Kiaei · 1989
A new structure for the VLSI implementation of bit/serial adaptive IIR filter is presented. The system is built at a bit level consisting of only gated full adders. This approach allows recursive operation of IIR filter to be implemented with minimal delay time and chip area. The coefficients of the filter can be updated in real time for the time invariant and adaptive filtering. The fourth order filter is implemented on a
