2.what is the limiting factor of clock frequency? Christoph Franck said:
Many things. Signal timing (both internal and external), power consumption, heat dissipation, transistor switching times, to name a few. I'm sure there's more. Jsathish Kumar said:
how when i increase my clock frequency may affect the transistor switching times. You have this the wrong way around! The switching time, etc, of a transistor is a property of its physical design; if you try to run it at a frequency higher than that design allows, it won't work. if my microcontroller is design with the cmos technology, this technology can accept higher than such "mhz" range Again, that's "MHz" = not "mhz". Sure, it is possible to design CMOS circuits that run very fast, but the mere fact that a chip uses CMOS technology does not mean that it has been designed to run at any particular speed. Again, you need to operate the chip within the specifications stated in the Datasheet |
