Abstract
By adding a DC signal to a smooth (non-square wave) clock of a divide-by-2 stage, an adjustable I&Q generator is implemented. An unbalanced differential pair is used as the clock buffer to improve lower frequency behavior by generating non-overlapping clocks and to prevent free oscillation problem
