Abstract
A device for high-speed clock generation may include an injection locking-ring oscillator (ILRO) configured to receive one or more input clock signals and to generate multiple clock signals with different equally spaced phase angles. A phase-interpolator (PI) circuit may be configured to receive the multiple coarse spaced clock signals and to generate an output clock signal having a correct phase angle. The PI circuit may include a smoothing block that may be configured to smooth the multiple clock signals with different phase angles and to generate multiple smooth clock signals. A pulling block may be configured to pull edges of the multiple smooth clock signals closer to one another.
