What is a time interleaved ADC?
Time interleaving is a technique that allows the use of multiple identical analog-to-digital converters (ADCs) to process regular sample data series at a faster rate than the operating sample rate of each individual data converter.
What is interleaved sampling?
Time Interleaved Sampling (TIS) is a technique to increase the real-time sample rate of a digitizer. TIS uses multiple analog-to-digital converters (ADCs) to sample the same input waveform, but at different relative phases.
What is aperture jitter?
This sample-to-sample variation in the instant the switch opens is called aperture uncertainty, or aperture jitter and is usually measured in rms picoseconds. The amplitude of the associated output error is related to the rate-of-change of the analog input.
What is a pipeline ADC?
Pipeline ADC is a mixed-signal system, which consists of sample and hold amplifier (SHA), sub-ADC, multiplying digital-to-analog Converter (MDAC) and bandgap voltage reference, comparator, switch-capacitor circuits and biasing circuits. This project set up a pipeline ADC design flow.
What is interleaved learning?
Interleaving is a process where students mix, or interleave, multiple subjects or topics while they study in order to improve their learning. Blocked practice, on the other hand, involves studying one topic very thoroughly before moving to another topic.
What is aperture time?
The aperture time (limitation 1) is the time required for the sampling gate to close after a sample is acquired. In an ideal situation, the aperture time is zero and the output signal of the S&H is proportional to the signal value immediately before the sampling instant.
What is the aperture setting on a camera?
A camera’s aperture setting controls the area over which light can pass through your camera lens. It is specified in terms of an f-stop value, which can at times be counterintuitive, because the area of the opening increases as the f-stop decreases.
Why flash type ADC is fastest?
1)It is the fastest type of ADC because the conversion is performed simultaneously through a set of comparators, hence referred as flash type ADC. Typical conversion time is 100ns or less. 2)The construction is simple and easier to design.
How do you do interleaved practices?
Interleaved practice – when you are learning two or more related concepts or skills, instead of focusing exclusively on one concept or skill at a time, it can be helpful to alternate between them (for example, if you are learning topic A and topic B, rather than practice only A on one day and only B on the next, you …
Why is interleaved practice effective?
Cognitive psychologists believe that interleaving improves the brain’s ability to differentiate, or discriminate, between concepts and strengthens memory associations. Because interleaving involves retrieval practice, it is more difficult than blocked practice.
What is aperture error?
Aperture uncertainty is the sample-to-sample variation in the encoding process. It has three distinct effects on system performance. First, it can increase system noise. Second, it can contribute to the uncertainty in the actual phase of the sampled signal itself giving rise to increases in error vector magnitude.
