Abstract
Phase mixers, clock signal generators, memories and methods for providing an output signal having a phase relative to the phase difference of input clock signals are disclosed. One such phase mixer includes a phase mixer circuit having inputs and an output. The phase mixer is configured to receive a plurality of input clock signals and generate an output clock signal at the output having a phase relative to the plurality of input clock signals. The phase mixer further includes an adjustment circuit coupled to the phase mixer circuit. In some phase mixers, a control circuit coupled to the phase mixer circuit and the adjustment circuit is included. The control circuit is configured to generate a control signal based on the input signals to adjust an electrical load-to-drive ratio of the phase mixer.
