Uh Oh... sorry,
I didn't explain exactly! What I meant was how to build the analog circuit (schematic), so that someone can test the fabricated DIE if it works without putting it on a PCB.
eg. if you have a Chip with ADC+DAC on it, you could put DAC and ADC in series and measure if in and output is the same Voltage! Putting it on PCB and testing afterwards is more cost expencive if the Chip doesn't work (of course this must also be tested!)
Is there some Book or reference which is about this topic?
