| Abstract: |
A divide-by-4.5 regenerative frequency divider for multiband orthogonal frequency division multiplexing ultra-wideband (UWB) applications is designed using a 0.18 µm CMOS technology. The divider operates at 7128 MHz and covers 14 sub-bands for a simple PLL-based frequency synthesiser. An efficient regenerative divider technique incorporating one single-sideband mixer increases the linearity and achieves a sideband rejection of 29 dB while consuming 7.3 mA from a 1.8 V power supply.
