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?

In my point of view of ur problem u'll need such circuit. For delay elements u can use RC delay or charge/discharge capacitor circuit with constant current and some amout of inverters.
