Abstract
Rotary traveling wave oscillator-based (RTWO-based) frequency multipliers are provided herein. In certain embodiments, an RTWO-based frequency multiplier includes an RTWO that generates a plurality of clock signal phases of a first frequency, and an edge combiner that processes the clock signal phases to generate an output clock signal having a second frequency that is a multiple of the first frequency. The edge combiner can be implemented as a logic-based combining circuit that combines the clock signal phases from the RTWO. For example, the edge combiner can include parallel stacks of transistors operating on different clock signal phases, with the stacks selectively activating based on timing of the clock signal phases to generate the output clock signal of multiplied frequency.
