A 1.6GHz/4.8GHz dual-band CMOS fractional-N frequency synthesizer for S-Band radio applications Conference Paper uri icon


  • A 1.6GHz/ 4.8GHz fractional-N frequency synthesizer in 0.18-m CMOS technology is presented in this paper. Its purpose is to generate the local oscillator (LO) signals for a fully integrated S-Band transceiver with a direct-conversion receiver (RX) and a dual up-conversion transmitter (TX) to avoid the frequency pulling problem. The synthesizer achieves phase noise of -141.3dBc/Hz at 1.62GHz and -132.6dBc/Hz at 4.86GHz (both at 3MHz offset), with reference spurs <-70.2dBc for the lower band (LB) and <-63.8dBc for the higher band (HB). Total power consumption is 18.2-22.7mW from a 1V supply for the VCO and 1.8V for the other synthesizer blocks. 2014 IEEE.
