Abstract
A mixer includes an input stage to convert an RF input signal to an output signal, and a mixer core to mix the output signal from the input stage with a local oscillator signal. The input stage may include an input cell having a first differential pair of cross-connected transistors, and a linearizer coupled to the input cell. The linearizer may include a second differential pair of transistors having first and second inputs coupled to the input terminals and first and second outputs coupled to the output terminals.
