模拟电子 你的PLD是亚稳态吗
This application note provides a detailed description of themetastable behavior in PLDs from both circuit and statisticalviewpoints. Additionally, the information on the metastablecharacteristics of Cypress PLDs presented here can help youachieve any desired degree of reliability.
模拟电子 DAC技术用语 (D/A Converters Defini
Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codec ...
