Embodiment Construction
[0038] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. The following examples are only used to illustrate and explain the present invention, but not to limit the technical solution of the present invention.
[0039] The present invention passes figure 2 The structure of an embodiment of a two-way parallel analog-to-digital conversion device is given. In fact, the present invention can be expanded and applied to the structure of more than two parallel analog-to-digital conversion devices.
[0040] Assume that the highest sampling rate of the existing ADC is 20GSa / s, and the required ADC sampling rate is 40GSa / s, so the design uses two ADCs (2 pieces of ADC) to work in parallel, and requires the skew of the output signals of the two ADCs Less than 5ps.
[0041] figure 2 The illustrated embodiment of the parallel analog-to-digital conversion device includes: a clock d...
