clock 1hz
Dear All.
After spending painful times to find some info about 1 Hz clock, I have finally decided to ask this to you all experts.
I am using 0.5um CMOS process in Cadence. For my chip design in biomedical applications, I need to have a 1Hz clock. By the circumstance of its use, I need it with low power consumption, and ON CHIP design.
I have designed a 1.3MHz VCO. If based on this, it requires a 20bit counter for 1Hz. It does not seem to be practical; not only the higher bit, but power consumption point of view too.
Any method or design idea please?
Thank you very much for your any comment.
