Abstract

A highly integrated transceiver for WiMedia UWB applications is presented. Implemented in 130 nm CMOS and operating from 1.2 V and 2.5 V supplies, it features direct conversion transmit and receive paths. Three PLLs with ring-oscillator VCOs are used in a fast-hopping (~2 ns) 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 -20.6 dB when operated in 480 Mbps mode.
