DESIGNING COMBINATIONAL LOGIC GATES IN CMOS
bwrcs.eecs.berkeley.edu6.2Static CMOS Design The most widely used logic style is static complementary CMOS. The static CMOS style is really an extension of the static CMOS inverter to multiple inputs.In review, the pri- mary advantage of the CMOS structure is robustness (i.e, low sensitivity to noise), good
