Abstract:
An apparatus comprising M time-interleaved analog to digital converters (ADC) that sample an input signal at M sampling phases, wherein M is equal to or greater than 4. A phase control circuit adjusts at least M−1 sampling phases of the M sampling phases. The phase control circuit comprises M−1 phase error detector circuits. Each phase error detector circuit detects a corresponding phase error for a corresponding sampling phase of the M−1 sampling phases based on a sample captured at a sampling phase of the M sampling phases immediately preceding the corresponding sampling phase and a sample captured at a sampling phase of the M sampling phases immediately subsequent to the corresponding sampling phase.
