Abstract
Embodiments herein describe a calibration circuit including a multi-phase clock generator configured to receive a clock signal and generate a multi-phase clock output, the multi-phase clock generator including a first injection-locked oscillator, a mixer, a current digital-to-analog converter (IDAC), and a voltage to current converter (VTOI), the IDAC and VTOI configured to fine tune offsets of the mixer and an input of the VTOI, and overcome phase errors from injection locking disturbance. The multi-phase clock generator further includes a pre-skew buffer configured to receive the multi-phase clock output from the multi-phase clock generator and generate multiple data signals and a phase interpolator (PI) configured to receive the multiple data signals from the pre-skew buffer and generate a shifted clock signal of the clock signal received by the multi-phase clock generator.
