Abstract
A high speed phase detector utilizes an integrated XOR/MUX circuit having a higher bandwidth and lower power than conventional designs. The XOR/MUX circuit combines the functionality of an XOR device in series with a multiplexer in a manner that increases the bandwidth of the function. In a practical implementation, the XOR/MUX circuit includes an XOR arrangement having a plurality of transistors implemented at a first transistor level and a plurality of transistors implemented at a second transistor level. The XOR/MUX circuit also includes transistors implemented at a third transistor level; these transistors are utilized by the multiplexer feature of the circuit.
