For optimal operation, the Clock and Data Recovery (CDR) circuit requires perfect quadrature between In-phase and Quadrature phase clocks. These clocks are used to sample the Data and the Edge information so as to enable the CDR to align the Receiver clock to the centre of Data eye. Any error in quadrature between the two clocks results in higher CDR jitter. Quadrature error mainly comes from the...
A semi-digital clock and data recovery (CDR) circuit implemented in 45 nm SOI process is discussed. The CDR uses two analog phase interpolators to generate in-phase and quadrature-phase clocks to sample incoming data. Due to onchip process variations, the phase interpolators exhibit a nonlinear behavior. More so, this behavior is not similar in the two phase interpolators, i.e. there is a mismatch...
