It seems like they would lose charge after just a few. Probably, because it is convenient -- the circuit can be simpler. A nine-bit counter can control everything: * The ninth-bit can control the discharge transistors directly; and, it can reset the comparators. * The lower eight bits can be the up-counter -- each voltage comparator can latch the current value of those bits into its POT output-register when its capacitor rises to the trigger voltage.
