Patent ID: 6847808

Claim:
A mixer circuit comprising: a first switching device having a first terminal, a second terminal and a third terminal; a second switching device having a fourth terminal, a fifth terminal, and a sixth terminal, the fourth terminal corresponding with the first terminal, the fifth terminal corresponding with the second terminal and the sixth terminal corresponding with the third terminal; the first and second switching devices being connected in parallel with the second terminal being connected to the fifth terminal to form an output and the third terminal being connected to the sixth terminal to form an input; the first terminal being adapted to receive a first signal for mixing, the first signal having a positive cycle and a negative cycle; the fourth terminal being adapted to simultaneously receive a second signal for mixing, the second signal having a positive cycle and a negative cycle with substantially a 180 degree phase shift in relation to the first signal; the input being adapted to receive a third signal for mixing with the first and second signals to produce a fourth signal at the output; wherein the first and second switching devices are complementary devices and wherein the first switching device is turned on by the first signal for at least a portion of the positive cycle of the first signal and the second switching device is turned on by the second signal for at least a portion of the negative cycle of the second signal such that distortion in the fourth signal is reduced.
