A 2.0-GHz submicron CMOS LNA and a downconversion mixer

A 2-GHz 'all transistor' LNA and a downconversion mixer have been implemented with a standard digital 0.5-/spl mu/m CMOS process. The LNA has been measured to have a noise figure of 5.4 dB and a 8.3-dB gain at 2.0 GHz. The Gilbert-type downconversion mixer with a 0-dB conversion gain to a differential 100-/spl Omega/ load and DSB noise figure of 11 dB has been measured. These processed circuits demonstrate the capability of submicron CMOS technology for high frequency applications.
