I read a book that mentions about the need to add capacitors in parallel with resistors in a resistive divider made up with many resistors in series and taps coming out of each resistor, in order to compensate for the PCB's parasitic capacitances, all the capacitors should have the same ratios as the resistors and the last capacitor should be variable and adjusted for best square wave symmetry, pretty much the same way as you would compensate a 10X probe on an oscilloscope.
How many of you have used this kind of arrangement?
If I remember correctly, the resistor values used in the example were relatively high, the highest resistor was in the Mega Ohm range, perhaps using much smaller resistors would negate the need for capacitors?
