Designing analog ICs can be a time-consuming and nit-picky process. As with the design of digital ICs, speed, power, and area (SPA) considerations are important. However, in the case of analog ICs, added challenges include gain, bandwidth, signal distortion, noise sensitivity, power supply sensitivity, thermal sensitivity, and more. All the major electronic design automation (EDA) […]
Analog Front End
Design an analog front end for a pH probe
pH probes, with their bipolar voltage outputs and high output impedance, need signal conditioning through an analog front end to make them compatible with measurement circuits such as A/D converters. By Marian Hryntsiv, Renesas Electronics People who work in healthcare, food and beverage, water treatment, chemical processing, agriculture, and environmental monitoring rely on pH meters […]
Software-configurable Analog Front End integrates ADC for industrial process control apps
Analog Devices, Inc.introduced the AD4110-1 Analog Front End with integrated 24-bit ADC for industrial process control systems. AD4110-1 is a universal input AFE with an integrated ADC that allows customers to design a “platform” input module that they can configure for multiple functions. This saves significant R&D cost, reduces time to market and requires less […]
Impedance/P\potentiostat Analog Front End handles biological, chemical sensing
Analog Devices, Inc. announced a new electrochemical and impedance measurement front end that enables the next generation of vital sign monitoring devices and intelligent electrochemical sensors. The AD5940 analog front end incorporates both potentiostat and electrochemical impedance spectroscopy (EIS) functionality on a single chip, allowing for sensor measurement in both time and frequency domains. The […]
