HIGH LINEARITY AND LOW NOISE MIXER |
摘要 |
<p>Circuits and methods for a mixer circuit involve having a first transistor with first and second terminals, where the first terminal is configured to handle an input RF signal. The mixer has a second transistor including a first terminal coupled to the second terminal of the first transistor, a second terminal configured to handle an input oscillator signal, and a third terminal configured to output an intermediate frequency (IF) signal. The IF signal includes a mixed product of the input RF signal and the input oscillator signal. A gate oxide thickness of the first transistor is less than a gate oxide thickness of the second transistor to provide enhanced linearity and a low noise figure. One or more of the mixers can be implemented in a receiver design.</p> |
