A high performance FIR filter dedicated to digital video transmission

| A digital lter 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 lter. Even though the coe cients to the lter are desired to be programmable, it is possible to change coe cients in the vertical y-back interval of television receivers. This allows the preloadability of coe cients to the lter such that each coe cient can be treated as a constant during the ltering operation. Motivated by such functionalities, a novel multiplier together with an FIR lter architecture is described, which has been designed by means of a 0.5 m double metal CMOS technology.
