What is power-supply noise attenuation (PSNA)?
Abstract— This paper discusses the power-supply noise attenu-ation (PSNA) in the frequency domain of four kinds of bandgap voltage reference that represent the basis of typical voltage ref-erences.
Is power-supply noise attenuation a fundamental design criterion?
However, an important param-eter, such as power-supply noise attenuation (PSNA), has not yet been analyzed explicitly in terms of its frequency behavior , , . This is despite the fact that in high-frequency ap-plications, this performance parameter becomes a fundamental design criterion.
How can a linear power supply reduce ripple & noise?
The most common solution to minimize that ripple and noise is to use linear power supplies cascaded to the DC-DC output rail. LDO based solutions come at the disadvantage of impacting power efficiency losses which becomes more challenging to manage in systems having multiple AFEs.
What is a remnant in a TAC-DC switching power supply?
In TAC-DC switching power supplies, even after rectifying and smoothing the AC current, there are still undulating voltage fluctuations—which can be described as “remnants” of AC. In the DC-DC converter section, where DC voltage is converted, high-frequency switching noise is superimposed on this voltage fluctuation.
What are the weaknesses of switching power supplies?
However, they also have one weakness unique to switching power supplies: high-frequency noise generated by switching current on and off with semiconductor elements at high speeds. The history of switching power supply technology has been synonymous with a struggle to achieve high efficiency, as well as a battle against noise.
How can high frequency power supply noise be reduced?
High frequency power supply noise is best reduced with low inductance surface mount ceramic capacitors connected directly to the power supply pins of the IC. All decoupling capacitors must connect directly to a low impedance ground plane in order to be effective.
