Built-in self-healing without added physical redundancy in time-interleaved ADCs

摘要

Examples are provided for a time-interleaved analog-to-digital converter (ADC) with built-in self-healing. The ADC may include multiple ADC slices. Each ADC slice may be configured to operate in one of a normal or a healing mode of operation. In the normal mode of operation, each ADC slice may convert an input analog signal to a single digital output signal in response to a clock signal associated with the ADC slice. In the healing mode of operation, each ADC slice may be operable to convert the input analog signal to two or more digital output signals in response to two or more clock signals. One or more of the digital output signals may replace one or more output signals of failed ADC slices. A first clock signal may be associated with the ADC slice. A second clock signal may be associated with another ADC slice of the plurality of ADC slices.
