Design of a 11-Band 3-10GHz Frequency Sy nthesizer for Multi-Band OFDM UWB Transceiver in 90nm CMOS Technology

A bstract—This paper describes the design of a 3-10GHz frequency synthesizer for Multi-band OFDM Ultra-wideband (UWB) transceiver in the 90nm CMOS technology. The frequency synthesizer operates in the band group 1, group 3, group 4, and group 5 with interference rejection at 5GHz, generating 11 carrier tones with fast hopping from a single independent reference frequency. An efficient frequency planning is proposed to minimize the number of RF blocks. The simulated frequency tone switching time is 2.9ns. The simulated overall power consumption is 121mW from a 1.0VDC supply. Index Terms—CMOS frequency synthesizer, ultra-wide band (UWB), multi-band UWB.
