Hi , The high frequency decouple needs 0.1 uf , 0.01uf ,0.000uf & etc. People use spice to figure out the exact caps required for decoupling the higher frequencies in a system. Can some one tell me what exactly needs to be simulated to derive at the cap values. Thanks in Advance. regards Sunil --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
