Abstract :
A 2 GHz up-converter uses 0.25 /spl mu/m CMOS. Current adding and self-switching mixers are used for 1 V operation. A -40 dBc LO leakage within a 20 mV offset is achieved using a DC offset canceller. The measurement results at 1 V supply are 6.7 dB conversion gain, 6.5 dBm OIP3, /spl plusmn/2 dB gain deviation from -33 to 75/spl deg/, and 49 mW consumption.
