Abstract :
A 10-b polar-to-Cartesian converter for generating digital sine and cosine waveforms simultaneously with a maximum sample rate of 540 MHz is presented. The converter is derived from a coordinate rotation digital computer (CORDIC) processor. Implementation details and the chip layout are given. The converter is implemented in a 1-μm 13-GHz triple-level interconnect bipolar process, requiring 1000 mW from a single 5-V supply. The die size is 25 mm2
