This section provides overview, applications, and principles of analog front end (afe). Also, please take a look at the list of 8 analog front end (afe) manufacturers and their company rankings.
An analog front end is an analog circuit that connects a device that detects signals, such as a sensor, to a device that processes digital signals.
It is sometimes called an AFE from the initial letters of Analog Front End. Since its main role is to adjust analog signals output from sensors, it is sometimes called a signal conditioning circuit as well.
Since analog signals detected by sensors are very weak and often contain many noise components, it is necessary to adjust these analog signals.
These days are often referred to as the era of IoT. IoT sensor modules also play an important role in the IoT era.
The basic system configuration is to detect physical phenomena occurring in the real world as analog values using sensors, convert them to digital signals, process them using microcontrollers and other devices, and then upload them to the cloud using wireless communication chips.
In this configuration, the analog front end (AFE) plays an important role along with the sensor and wireless communication chip, and must be properly designed to enhance the performance of the IoT sensor module.
The components of an analog front end are A/D converters, amplifiers, and semiconductor chips. Amplifiers include instrumentation amplifiers, operational amplifiers, and transimpedance amplifiers.
Semiconductor chips are often high-performance, ranging from discrete products with a high degree of freedom to integrated products that integrate many functions. Multiple integrated functions are relatively easy to use.
Many highly integrated analog front-end chips are also available in the market, such as those that integrate analog front-ends into pressure sensors, temperature sensors, etc. Amplifiers, A/D converters, and other components are integrated into a single chip, which also has the ability to adjust the characteristics of the AFE section and the current source depending on the characteristics of the sensor element.
In addition, there are analog front ends for optical sensors that are integrated with optical elements and available as a package, and those that only provide AFE functions without optical elements and allow the user to freely select the optical elements to be connected.
