Hello,
I am facing a critical problem of generating the synchronized clock signals for two analog circuits which have different grounds. As shown in the attached figure, the clock generator has the single input clock signal from outside. The clock generator should send two different control signals to two analog blocks. The challenge here is the two analog blocks have different grounds, one (ANA_1) is the same as clock generator, it is fine. But the other (ANA_2) has higher ground voltage, I really don't know how to design the control signal for ANA_2. The control signals for ANA_1 and ANA_2 should be synchronized. Does anyone have possible solutions to solve this problem? I appreciate any comments about it, even somebody can tell me this idea doesn't work at all. Thank you.
