Abstract
A mixer includes first and second differential input pairs that include first and second transistors. First and second bias transistors receive a first signal of a differential input signal that is the one of a first phase and a second phase, and that respectively communicate with first terminals of the first and second transistors of the first differential input pair. Third and fourth bias transistors receive a second signal of the differential input signal, and that respectively communicate with first terminals of the first and second transistors of the second differential input pair. First and second capacitive elements have first and second ends that respectively communicate with the first terminals of the first and second transistors of the first and second differential input pairs. Four current sourcing elements respectively communicate with first terminals of the first, second, third, and fourth bias transistors.
