A 0.13 /spl mu/m CMOS UWB transceiver

A direct-conversion UWB transceiver for mode 1 OFDM applications employs three resonant networks and three PLLs. Designed in a 0.13 /spl mu/m CMOS technology, the transceiver provides a total gain in the range of 69 to 73 dB, an NF in the range of 5.5 to 8.4 dB across three bands, and a TX P/sub 1dB/ of -10 dBm. The circuit consumes 105 mW from a 1.5 V supply.
