An innovative design with simulation results of a low-voltage bulk driven mixer for direct conversion receiver is presented. The circuit is designed in a 65 nm digital CMOS process without analog extensions. It offers a conversion gain of 22 dB at a clock frequency of 1.5 GHz for GALILEO/GPS applications. The design is capable of operating at up to 7 GHz with only 3 dB gain decrease. The simulated...
This paper presents a low power CMOS down sampling micromixer in 65nm with an improved input stage. It is able to handle a superimposed DC current on the input port without degrading circuit performance. The mixer was fabricated in a triple-well process. A conversion gain of 17dB is achieved while only consuming 780muW from a 1.2V voltage supply up to a 3dB clock frequency of 600MHz. The gain decreases...
