    Can divided_by_3 circuit get quadrature output?

    Usually, we can get quadrature output through divided_by_2 circuit, but what about divided_by_3? I hope to get some reference for this. Thanks1

    About bandwith of PLL

    For the LPF in PLL, is the bandwith of the PLL only related to the R?Is the C1 and C2 connected with the bandwith? Thanks!

    need help on uwb synthesizer

    There are two kinds of standards about UWB. One is Wimedia/MBOA, which needs fast setting PLL. The other one is Pulse based UWB, which needn't PLL.You can read some papers from ISSCC2004-2006 to study that.
