The key circuit design includes a sample-and-hold gain circuit using switched-capacitor to sample or hold the signal and a preamplifier-latch comparator using two-phaseclock.
The difference clock delay match technology adjusts the two channel AD analog clockphase and implements the two way AD uniformly-space sampling.
差分时钟延迟匹配技术通过对两路AD的采样时钟进行相位调整,实现了两路AD的等间隔采样。

To test for this scenario, rig up an external phase-locked dual-clock source with a knob that intentionally adjusts the phase relationship of the two clocks.
