How to use an ideal diode controller as a scalable input bypass switch in solar

Authored by Yang Wu, Abhijeet Godbole and Dilip Jain. Solar optimizers can now support higher input voltages thanks to efficiency improvements gained by lower conduction losses for a given power level and lower system costs. This article discusses a scalable bypass circuit solution using a floating-gate ideal diode controller to address challenges related to bypass switches with wide voltage support in solar power applications.

Designing 4mA to 20mA loop-powered transmitters

Industrial field transmitters are essential to process automation. The majority of these transmitters communicate with the PLC or DCS systems through a 4 to 20mA current loop, which offers a highly robust connection in harsh industrial environments. This article explains the design targets and boundaries of a 4 to 20mA transmitter circuit, as well as different implementations of loop-powered, 4 to 20mA transmitters, performance differences and where each is used.

How anti-aliasing filter design techniques improve active RF converter front end

Authored by Rob Reeder. When using an anti-aliasing filter between the output of an FDA and the input of the ADC, there will be several trade-offs to consider during the implementation process. These include filter order and topology, or whether you will need back termination or series resistances to enhance the interface between the FDA and the ADC. In this paper, we explain these AAF nuances and how to circumvent any huddles encountered in your next design.

Impact of voltage reference noise on ADC ENOB and noise-free resolution

Authored by Jackson Wightman. While every analog-to-digital converter (ADC) has a specified number of bits, perhaps it is more important to consider the effective number of bits (ENOB). Careful voltage reference selection and implementation are essential to improve the precision and accuracy of your ADC signal chain. Learn how to implement a voltage reference in to improve performance in this article.
