8bit SAR ADC ..#2

hi everyone;
in my term project i am required to desig an 8 bit SAR ADC which will be able to convert analog signals up to 5v and in 10mhz-50mhz range. Successive approximation register(SAR) design will be on xilinx and loaded to a fpga card.I have problems in designing an appropriate sar.if you have any 8 bit sar verilog code or 8 bit SAR circuit please share them with me.
the second problem is the sample and hold part.if you have any documents on the S/H circuits used in adcs i will be very happy to see them.
