Slew Rate vs. Rise Time: Not Quite The Same - EDN
WEBFeb 26, 2019 · In What’s that signal’s bandwidth?, we took a look at the classic relationship between rise time and bandwidth.A discussion of rise time often leads to the question: is this the same thing as slew rate? Slew Rate vs Rise Time. Let’s take a look at slew rate, a concept similar to rise time but with some important differences.
Setup and Hold Time Equations and Formulas - EDN
WEBAug 10, 2012 · Setup and hold time equations. Let’s first define clock-to-Q delay (T clock-to-Q).In a positive edge triggered flip-flop, input signal is captured on the positive edge of the clock and corresponding output is generated after a small delay called the T clock-to-Q.The flip flop can only do the job correctly if the data at its input does not change for some time before the clock edge (T setup ...
Setup and Hold Time Basics - EDN
WEBApr 19, 2012 · Whenever both nMOS and pMOS are turned on, any signal ‘1’ or ‘0’ passes equally well without degradation. The use of transmission gates eliminates undesirable threshold voltage effects which give rise to loss of logic levels.

Using an op amp as a comparator - EDN
WEBJan 15, 2021 · In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative feedback, which normally keeps the op amp operating in the linear region. However, op amps can also be used as comparators, which causes them to operate non-linearly.
Eye Diagram Basics: Reading, Analyzing and Applying
WEBDec 16, 2011 · How to read an eye diagram. A properly constructed eye should contain every possible bit sequence from simple alternate 1’s and 0’s to isolated 1’s after long runs of 0’s, and all other patterns that may show up weaknesses in the design.
Audio levels, dBu, dBV, and the gang: What you need to know
WEBApr 18, 2017 · But before delving into the interfaces and their differences, we need to look at the purely audio phenomenon called dBVU. VU Meters We’ve all seen “VU” (volume unit) meters on audio equipment, but the truth is, very few of them are true VU meters.
