Abstract

Systems, devices, and methods related to frequency divider circuitry are provided. An apparatus includes frequency divider circuitry including a first node to receive an input signal; fractional divider circuitry to generate, based on the input signal and a frequency-division ratio, a first signal having a first series of pulses with adjacent pulses triggered by opposite edges of the input signal, wherein the fractional divider circuitry includes first signal selection circuitry; balancer divider circuitry to generate, based on the input signal, a second signal having a second series of pulses aligned to the first series of pulses, wherein the balancer divider circuitry includes second signal selection circuitry triggered by opposite edges of the input signal than the first signal selection circuitry; and a second node to combine the first signal and the second signal.
