Abstract:
An electronic signal sampling circuit comprising:a first input for receiving an electronic signal; a sampling clock input for receiving a sampling clock signal; a first sampling circuit, electrically coupled to the first input and to the sampling clock input and responsive to the sampling clock signal, for sampling the electronic signal to determine a first pair of boundary reference voltage signals that bound the voltage of the sampled electronic signal, and further to convert the sampled electronic signal to provide a first digital representation thereof at times indicated by the sampling clock signal; and a second sampling circuit, electrically coupled to the first sampling circuit, for sampling an interpolated signal, that is different than the electronic signal, and corresponding to the first pair of boundary reference voltage signals that bound the voltage of the sampled electronic signal, and further to convert the sampled interpolated signal to provide a second digital representation of the sampled electronic signal at times indicated by the sampling clock signal, the first digital representation and the second digital representation being provided as output of the electronic signal sampling circuit.
