A Direct-Conversion CMOS RF Receiver Reconfigurable From 2 to 6 GHz

A CMOS direct-conversion receiver with only one signal path is reconfigurable from 2 to 6 GHz in the RF band and from 3.6 to 54 MHz in the channel bandwidth. By employing a voltage feedback in a common-gate low-noise amplifier (LNA), the input matching of the LNA can be reconfigured for each RF band...
