Abstract
A CORDIC processor for wire telecommunication is integrated in a 0.5μm CMOS technology. The CORDIC (coordinate rotation digital computer) processor reduces the circuit complexity by performing a sequence of elementary rotations using shift and add operations without multiplications. Hard wired-logic eliminates the shifter and includes pre-calculated arctan angle values. The average power consumption is 76mW with 50MHz clock and 5V power supply. The fabricated modulator consumes 24mW at 61.44MHz sampling rate and 5V power supply
