Abstract
A frequency divider circuit comprises a first divider chain including at least one first divider cell and a second divider chain coupled to the first divider chain to form an extendable divider chain. The second divider chain includes at least one second divider cell with a respective reset control. An effective length of the extendable divider chain may be altered, dynamically, via the respective reset control. Altering the effective length, dynamically, enables a division ratio of the frequency divider circuit to be changed, dynamically. The frequency divider circuit may be advantageously employed by applications that rely upon a dynamic division ratio, such as a fractional-N (frac-N) phase-locked loop (PLL).
