ABSTRACT:
A high speed, static, BiCMOS comparator circuit. Though static, the circuit operates at nearly dynamic speeds. The circuit consists of two stages. The first stage generates XOR and XNOR outputs given two bit strings. The second stage detects hit and miss separately using the XOR and XNOR inputs. The second stage generates signals for both hit lines and miss lines.
