High Frequency Circuit Wiring techniques in PCB Layout 1. Multi-board wiring High-frequency circuits often have a high degree of integration and a high wiring density. Using a multi-layer board is not only required for wiring, but also an effective means to reduce interference. In the PCB Layout stage, a proper selection of printing board sizes of a certain number of layers can make full use of the middle layer to set shielding to better achieve near

Transferred from: Http://ticktick.blog.51cto.com/823160/305471 I have been working on an embedded system and drawing a schematic diagram recently. Finally, in order to ensure the accuracy of the schematic diagram, it took me nearly two weeks to check the schematic diagram. Here, I would like to summarize my experience in checking the schematic diagram for your reference, you are welcome to point out something wrong. After we draw the circuit schemati

1-2-2. Output Voltage filter circuit of the tandem switch power supplyMost of the output of the switching power supply is DC voltage. Therefore, the output circuit of the general switching power supply has a rectifying and filtering circuit. Figure 1-2 shows the working principle of the series-connected switching power supply with the rectification and filtering

In a microservices architecture, the service is split into services according to the business, and the service and service can call each other (RPC), which can be invoked with Resttemplate+ribbon and feign in spring cloud. To ensure their high availability, a single service is typically deployed in a cluster. Due to network reasons or their own reasons, the service does not guarantee that 100% is available, if a single service problem, call the service will be a thread blocking, if there is a la

In a distributed architecture, the role of the circuit breaker pattern is similar, when a service unit fails (similar to a short-circuit with electrical appliances), through the fault monitoring of the circuit breaker (similar to a fuse fuse), to the caller returned an error response, rather than a long wait. This does not cause the thread to fail to be released

Programmable Active Filter Circuit Based on Single Chip Microcomputer Control [Date:] Source: foreign electronic components Author: Zhao shiqiang, Zhou yijian, Liu Xia [Font:Large Medium Small] 　 1 IntroductionActive Filter is widely used in digital signal processing, communication, and automatic control, but it is difficult to design a variable wide band active filter.

Brief introductionSpring Cloud provides a hystrix fault-tolerant library to temporarily invoke an alternate method when the service is unavailable, and a downgrade strategy is implemented for the method that configures the circuit breaker. This article creates a product microservices, registers to the Eureka Service registry, and then we use the Web Client Access /products API to obtain a list of products that, when a product service fails, calls the

Short-circuit OPERATOR: and | or short-circuit operator should remember one principle: 1. Any number and operation must be performed on any number 0 and any number. 00 and any number, or operation must be performed on any number 1 and any number, or operation must be performed on any number. Therefore, short-circuit operators execute commands based on this princi

Linear Technology ' s recently introduced LTC4300 chip buffers i²c clock and data lines to and from a hot-swappable card. This task was difficult because the IC must work bidirectionally, meaning so can simultaneously and actively drive BO Th sides. However, as is sometimes the case, you can replace a complicated circuit by a simple one without much loss of performance. For example, transistors and resistors replace the entire IC (Figure 1). The

This article mainly introduces the main causes and countermeasures of chip capacitor (multilayer slice ceramic capacitor) rupture and failure.There are three main points:1. The main cause of problems such as rupture and short circuit is not due to the chip capacitor itself, but more factors related to the whole installation and welding process of the capacitor.2. rupture and failure are the most common and major problems encountered in the use of SMD

Positive feedback and Negative Feedback Positive feedback is used to increase the output after feedback is introduced. Negative Feedback is called to reduce the output after negative feedback is introduced. Adding a net input is called positive fe

; Edge[ecnt].next = Head[u]; Head[u] = ecnt++; } Where ecnt is the number of edges, this function adds this edge to the beginning of the same edge as the previous starting point, and the head array is generally initialized to -1,ecnt initialized to 0. The order in which this is added and read is reversed, but does not affect the correctness of the result. The examples below all use chain forward stars.Two, the shortest path algorithmThe shortest path algorithm is generally divided into

formation factor of electrolytic capacitance ESR.Iii. reasons for choosing low ESR CapacitorsNow electronic technology is moving towards the design of low voltage and high current circuit, the supply of voltage to the components of the trend is getting lower, but the demand for power has not decreased. According to the P=UI formula, to obtain the same power, the voltage is reduced, it is necessary to increase the current. For example, Intel, AMD's la

Introduction: The teacher recommended a lot of online courses, one of the most love circuit. After returning home, the winter vacation lived in the busy stable, began the daily accumulation of learning.Not long ago, the Mooc of Tsinghua University, "Circuit principle", big call fun! Learning knowledge has never been organized and simple!The course features are summarized as follows:• Knowledge is highly sum

ecl circuits typically has relatively small logic spans of approximately of MV. Because of the small span, to-drive TTL circuits from ECL levels normally entails the use of level converters, such as the MC10125, or comparators. Such circuits is relatively power-hungry and expensive. However, they is sometimes simply unnecessary. The circuit infigure 1allows-trigger some TTL circuitry by generating a fairly short negative-going pul Se from the trailing
