Özet
A highly integrated transceiver for WiMedia UWB applications is presented. Implemented in 130nm CMOS and operating from 1.2V and 2.5V supplies, it features direct conversion transmit and receive paths. Three PLLs with ring-oscillator VCOs are used in a fast-hopping (similar to 2ns) frequency synthesizer. On-chip calibration is used by several blocks for I/Q mismatch, filter tuning, DC offset cancellation and power control. The transceiver achieves a transmit EVM better than -20.6dB when operated in 480Mbps mode.
