Abstract
- A wideband (6–20 GHz) SiGe adaptive image reject mixer with an IF bandwidth of more than 1.8 GHz is presented. The mixer can be “self-healed” to deliver consistent performance across band by nullifying the effects of process variations, environmental changes or aging and can be adapted to different specifications. A conversion gain greater than 15 dB, an image rejection ratio (IRR) exceeding 35 dB and an output 1-dB compression point greater than 10 dBm were obtained in measurement. An automated self-healing procedure is shown to be effective for improving the measured performance of the mixer. The mixer was fabricated in a 150 GHz peak f T 200 nm SiGe BiCMOS process and consumes 215 mA of current operating off a 4 V rail.
