Abstract :
A digital filter is one of the fundamental elements in the digital video transmission, and a multiplier acts as the key factor that determines the operation speed and silicon area of the filter. Even though the coefficients to the filter are desired to be programmable, it is possible to change coefficients in the vertical fly-back interval of television receivers. This allows the preloadability of coefficients to the filter such that each coefficient can be treated as a constant during the filtering operation. Motivated by such functionalities, a novel multiplier together with an FIR filter architecture is described, which has been designed by means of a 0.5 μm double metal CMOS technology
