Abstract
An analog/digital converter providing a high conversion speed and resolution while greatly reducing the number of circuit elements. The A/D converter in a first embodiment is a 6-bit resolution flash A/D converter made up of a 3-bit lower A/D conversion section and a 3-bit upper A/D conversion section. The lower A/D conversion section has a stage 1 comparator section 10, containing a specified number of comparators which compare the analog signal to comparison reference voltages of differing values, stepped in equal increments, an adder 12 which combines, in a specified relationship, the outputs from each of the comparators in this stage 1 comparator section 10 and adds them in each group, a second comparator section 14 which combines, in a specified relationship, the specified number of addition results from this adder 12 into pairs and compares these pairs, and a pre-encoder 16, which converts the specified number of comparison results obtained by the second comparator section 14 into 8 binary logical outputs which can be interpreted by lower encoder 18.
