How to make a better device Good performance faster and less power consumed Low cost more compact and use less area

Electrical behavior of cmos Steady-state behavior when output is hold on 1 or 0 Dynamic behavior when output is changing

Codes in binary system BCD codes: for decimal digit Gray code: for numbers in binary system; AsCIi code: for characters ey point Use n bits. we can make 2n different words: To make n code-words. you must use logn bits
