Library setup time是什么

WebTo settle within 1 LSB of full scale implies the settling accuracy of the A/D is ±1/2 LSB. Thus, a 10-bit system will require the op amp to settle to half of one part in 1024, or approximately 0.05%. A 12-bit system will require settling to half of one part in 4096 (0.01%). The requirements for 14-bits and greater are yet more demanding. Web19. sep 2015. · Technology.

WebSetup time is defined as the minimum amount of time before the clock's active edge that the data must be stable for it to be latched correctly. In other words, each flip-flop (or any sequential element, in general) needs some time for the data to remain stable before the clock edge arrives, such that it can reliably capture the data.
