Abstract

The A/D coder compares the analog input voltage with a series of reference voltages and requires no logic circuitry at the comparator's output. It is therefore faster than similar coders. The result of each comparison is added to the inverted result of the following comparison to form a first sum signal. The inverted result of each comparison is added to the result of the following comparison to form a second sum signal. The two sum signals are compared to determine the least significant bit. Each first sum signal is compared with the corresponding second sum signal to determine the 2., 3. etc. bit up to the highest significant bit.
