Analysis of a switching power supply circuit diagram. +310V voltage passes through 1R1, 1R2, and the voltage regulator diode 1D1 (to prevent the gate from breaking down due to excessive voltage) to pr...
The performance of STM32F429 is really good, and many people covet it. The purpose of the survey here is that if there are many people who respond, I am willing to make PCBs for everyone. [/font]...
Digital-to-analog converters (ADCs) provide the critical conversion of analog signals to digital signals in many systems. They perform amplitude quantization of an analog input signal to a binary fini...[Details]
In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
To ensure the success of China's TD-SCDMA network commercialization, operators and equipment suppliers need to conduct a large number of tests on networked equipment, among which RF testing is...[Details]
Third generation (3G) mobile phones offer a variety of features with more functionality. As consumers enjoy the latest and better features of these communication devices, they continue to demand lo...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m～1kHz), audio (20Hz～20kHz), video (20kHz～10MHz), radio fre...[Details]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pressur...[Details]
0 Introduction
At present, the analysis of intra-pulse signals in pulse radar has always been a hot topic and difficulty in research. How to measure the intra-pulse carrier frequency more ...[Details]
introduction
The most common flight state of a fixed-wing aircraft is horizontal flight. If it is allowed to fly at a large angle, the action cannot be maintained all the time. If it is al...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
Power Integrations (PI) has introduced three charger/adapter reference designs using its new LinkSwitch-II series of AC-DC switching power conversion ICs. The new LinkSwitch-II devices use high-pre...[Details]
Electrocardiogram is an important means of diagnosing heart disease. However, due to various reasons, it is difficult to capture abnormal electrocardiograms with ordinary electrocardiographs. Although...[Details]
Introduction
High voltage power supply is an indispensable part of nuclear radiation detection instrument, which supplies high voltage to nuclear radiation detection devices (such as prop...[Details]
