Abstract
An area-efficient delay cell utilizes transistor stacks to control positive feedback responsive to a counter code, thereby controlling the hysteresis and overall signal delay of the cell. The code-delay response of the cell can be modified by freezing the counter code at a convenient value. Linear superposition of the responses of one modified cell connected in series with one unmodified cell provides a more linear overall response and reduces jitter when used in a delay locked loop.
