Abstract :
This paper describes modification of conventional CML gates as used in frequency dividers by replacing the tail current source with a resistor. The custom gates are demonstrated as building components of frequency dividers implemented in a 0.13 mum CMOS technology. The frequency of operation spans from 20 MHz up to 11 GHz from a 1 V supply. The improvements of the phase noise of the frequency dividers and layout savings are reported.
