Abstract
The paper presents two designs of high-frequency, broadband frequency dividers. The designs are optimized for stability across process variations and high operating frequencies. The first design divides an input frequency range of 4-44GHz, drawing 4.4mA from a 1.2-V supply. The minimum input power is -5dBm at 40GHz. No performance degradation is observed at 50/spl deg/C, and only 16% degradation at 75 /spl deg/C. A second divider operates from dc-37GHz, consuming only 1.6mW at 30GHz. By not using inductive peaking, the designs achieve high bandwidth and small area (19/spl mu/m by 40/spl mu/m).Keywords
