KCC's quizzes AQQ260 about a technical article correction

1)  Error =>... proportional to the unknown voltage (TINT/VIN).

2)  ...The time it takes (TINT) for the integrator to trip the comparator is inversely proportional to the unknown voltage VIN and integrator gain (1/RC).  TINT=RC(Vref)/Vin.  In this...

      Change Vin to 1/Vin in fig. 1b.

Thanks retiredEE ! You have indeed localized the error in the article. And to be in accordance with the circuit diagram, the text should be modified in saying TINT is in fact inversely proportional to Vin. However, considering the whole article dedicated to ADC architectures, the "correction" has to be beyond: how to correct both the text and circuit in order to come with a right overal description of a correct single slope analog to digital converter. By keeping the circuit unchanged the target is not met obviously....
