ABSTRACT:
An analog to digital converter includes a comparator, an up/down counter and a pulse width modulator. The analog input to the comparator initially causes the counter to count up. The counter output is the converted digital word. The word is used to vary the modulation duty cycle of the modulator output which is compared with the analog input to the comparator. When the modulator output exceeds the analog input, the comparator output changes and the counter counts down, maintaining a digital output from the counter at the value of the converted analog signal.
