Abstract :
The architecture of an iterated FIR (finite impulse response) filter using radix-4 serial/parallel multipliers and radix-4 serial adder/subtractors is presented. The architecture is targeted for ultra-high-speed technologies, in particular GaAs MESFET and HEMT (high electron mobility transistor) technologies. A serial arithmetic approach is proposed for this high-speed but relatively low integration level technology in order to reduce the size of the integrated circuit. The authors give a description of the iterated FIR filter structure and discuss two possible approaches to implementing the FIR algorithm in GaAs
