Design of an Efficient Frequency Synthesizer used For Multi-Band OFDM Abstract— This journal describes the design of a 3GHz -10 GHz [1] frequency synthesizers for Multi-band OFDM in an Ultrawide band (UWB) transceiver at 180nm CMOS technology. As there is a requirement of high speed data rate, reduction in chip size and low power consumption for wireless devices there is demand for high speed complex […]
