Thank u, evilguy.
I want to design mixed signal. An 8-bits integrating (dual-slope) A/D converter. In this design, there are analog parts (integrator, comparator, bandgap voltage reference) and digital parts (counter, latch, register, switch,...)
I'll try your way 'cause it's really difficult to use custom digital part way in this project. Do you agree?

On the same occassion, can anybody give me some documents relate to 8-bits integrating (dual-slope) AD converts design?? especially the digital control part and in the 0.18u process
Thanks very much.
Regards.
