need clock generating circuit

[asueee0]

a clock of 10MHZ is given, we need this clock to generate another clock that has the same frequency as the original one, so that these two clocks could be used to control a switch cap circuit, any one have any idea how how to design this clock generating circuit?

The circuit is usually used in sigma-delta modulator.

Thanks for your sharing.

not only for sigma-delta modulator, this circuit is widely used for switch capacitor circuit to generate two phase non-overlap clock

 

[renwl]

yes. I dont think the clkgen of sigma-delta is different.

where is it from, could i have more details? if the clock frequency is slightly diferent, do i have to modify anything? to implement those gates (use complementary cmos logic)in 0.35um technology,what need to be paid attention? is there any simpler circuit could do the job?

10MHz is not a high frequency. maybe there're easier design. you can try it.
all the problems can be found out by simulation,I believe.
