cmos digital multiphase clock -patent

I want to generate a multi-phase clock for swithed-capacitor circuit such as the figure below. The clock freq. is about 100kHz and the delay between phases is about several handred ns.

Can any one give me some advice?

A 14-b 20-MSamples/s CMOS Pipelined ADC


A low power 10 bit, 80 MS/s CMOS pipelined ADC at 1.8V power supply

Also interested in the design technique of adc, mistdark@uestc.edu.cn.
