Abstract:
A clock and data recovery (CDR) circuit for data sampling includes a sampler, a phase detector, a proportional-integral (PI) controller, and an oscillator. The sampler receives a data signal and a clock signal, and generates first, second, and third sampled signals. The phase detector receives the first, second, and third sampled signals, and generates first and second early-late vote (ELV) signals. The charge pump steers a current signal into or out of one of summing nodes based on the first and second ELV signals. The integrator circuit receives the current signal from one of the summing nodes, and generates a first control signal. The proportional circuit receives the first and second ELV signals, and generates a second control signal. The oscillator receives the first and second control signals from the integrator and proportional circuits, respectively, and generates a clock signal for sampling the data.

Claim (Index 3):
The CDR circuit of  claim 2 , wherein the charge pump includes a current-source circuit for receiving the CMFB control signal, and generates the current signal that is steered into or out of one of the summing nodes based on the first and second ELV signals.
