Abstract
A high speed impedance matching circuit suitable for use in high speed semiconductor integrated circuits matches the output impedance of a semiconductor device to the impedance of other devices such a computer system bus thereby reducing signal reflections caused by impedance mismatches and which can adversely affect the operation of a high speed computer system. The impedance of an output buffer is matched to the impedance of an external resistor.
