Power module design of high-speed analog-to-digital converter based on switching power supply (with circuit diagram)

Probe domestic switch needle KG-300K needle head diameter is 3.0mm normally open switch needle
MOS power IC full range
L0504-Murata muRata common mode inductor 90Ω 150mA

Summary:
This article demonstrates that the analog-to-digital converter can be powered directly from a switching power supply without careful performance degradation, while carefully following design practice techniques. Compared to the ADP1708 linear power supply, the performance of the converter did not decrease when powered by the ADP2114 switching power supply. The use of switching power supplies can increase power efficiency by 30% to 40% and significantly reduce total power consumption (even more than simply selecting a lower power converter). In many systems, these devices require continuous operation, so switching power supplies can significantly reduce operating costs without sacrificing performance.

Zcoin is a digital currency that aims to create a truly anonymous method of trading.

One big obstacle to Bitcoin's emergence as an electronic currency is that all its transactions are visible on a public blockchain. As a result, Bitcoin's interchangeability has been controversial. Some people or companies (mainly exchanges) will not accept bitcoins for certain addresses. Such scrutiny runs counter to Bitcoin's core philosophy.

Zibo is the latest attempt to create a currency that can be verified without knowing the input and output of a cryptographic signature. This is called a zero-knowledge proof. DASH and Monero are two other digital currencies that are also trying to solve the same problem using different encryption methods.

The whole world is buzzing about zeros. A lot of people respect the Zibo development team. They have received investments from prominent Bitcoin venture capital firms such as Pantera, Distributed Capital, and Digital Currency Group. Bitcoin luminaries such as Roger Ver, Erik Voorhees, Barry Silbert, and Li Xiaolai have invested in Zcoin out of their own pockets. Confirmation bias is an important factor in why investors choose one project over another. If the leading players in the bitcoin industry are investing, it must be a good thing, right?

Unfortunately, Zcoin did not issue an initial currency offering (ICO) to investors. ZEC is the three-digit currency code for zerocoin. ZEC will initially be mined, just like Bitcoin. But unlike Bitcoin, which was full of unknowns when it was first launched, ZEC's founding block is a high-profile one. ZEC prices have skyrocketed because of extreme demand.
