1. Design Overview 1. Design Intent The rapid development of medical imaging technology continues to promote the progress of modern medicine. CT, MRI, and PET are widely ...[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]

Designers of hearing aids have stringent requirements. Hearing aids must be small enough to fit in or behind the ear, operate on ultra-low power, and be free of noise or distortion. To meet these requ...[Details]

With the development of the automobile industry, the complexity and information density of automobile information systems are increasing. Displays are no longer just basic centralized instrument di...[Details]

TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[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]

There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows: Oscilloscope pre-stage attenuation c...[Details]

introduction In engineering practice, ultrasonic waves are often used to measure distances because of their strong directivity, slow energy consumption, and long propagation distance in th...[Details]

1. Introduction The intelligent detector discussed in this paper is an integrated semiconductor photodetector. Compared with traditional semiconductor photosensitive devices, its most ...[Details]

Introduction Wireless operators are driving demand for broadband and data rates by offering enhanced data services to increase average revenue per user (ARPU). The need to provide users with ...[Details]

Industrial control often requires multi-channel fault detection and multi-channel command control (this multi-task setting is very common). A single CPU chip is difficult to directly complete ...[Details]

Abstract: Aiming at the performance requirements of the control system for micro-sized walking robots, a control system that can be used for multi-joint driving of walking robots is introduce...[Details]
