ABSTRACT:
A parallel comparison type A/D converter which can produce a digital output with improved monotonic operation.
The A/D converter comprises a plurality of comparators for comparing an analog signal with a plurality comparison voltage, and a plurality of logic gates each having a first input terminal of a positive logic and a second input terminal of a negative logic, one of the first and second input terminals receiving an outpt signal from one of the comparators of a certain weight and the other of the first and second input terminals receiving an output signal from the comparator having a weight subsequent to the certain weight. The threshold values of the first and second input terminals are made different from each other.
