incomplete Σ Δ ADC -- since i don't quite grasp it's operation yet -- just to see where it goes . . .
the CLK not verified as opt. for this v. but for it's predecessor that was tracking the analog input with the analog summer - the D-Flop output was basically the same only it was without the U/D counter ...
the following shows the effect of resetting the U/D count to 0 after specific time interval (number of clocks)
-- the effect with pure*sine wave here is the "reset" (actually a periodic substraction of some constant) integrates the derivative of it* back to it* -- it's a lot of tedious testing to determine what to actually implement in circuit . . . but the following is showing the prev. test being on the right track
what is surprising here is that the lesser number of clocks gives better results ???

CD4003 (К176ТМ1)
e.g. what to do with old stuff ...
Simplified CMOS setup - to gain reasonable simulation speeds ...
one half of the chip (the 4011 and -69 have the same I/O/supply scheme) :
extendable counter setup :
