Abstract :
An all-digital CDR for a pulse-based inductive-coupling interface is presented, which uses a TDC with free running oscillator for seamless oversampling and an all-digital DLL. The TDC utilizes an error correction scheme to reject noise pulses and the DLL recovers the phase information based on a 32-bit digital comparator. Peak-to-peak jitter is 12.2ps with 1.2Gb/s at 1.2V, whereas energy consumption is 4.7pJ/b with 1.2Gb/s at 0.6V.
