Here’s a nostalgic vibe of an awesome analog chip from the 1990s era that’s still making an impact in audio designs.

Hepatitis B virus (HBV) infection remains a major global health concern, necessitating the development of sensitive and reliable diagnostic methods. In this study, we propose a novel approach to ...

From 1963 to 1966 he was employed by Fairchild Semiconductor, Mountain View, Calif., where he headed the development of its linear integrated-circuit line. His designs include the µA702, µA709, µA710, ...

This paper presents an on-chip common-mode cancellation circuit which increases the immunity to electromagnetic interference (EMI) of integrated CMOS operational amplifiers when EMI is injected into ...

Conversely, when the Liquid Spark Headphone Amplifier was introduced in 2018 (a year after Alex Cavalli announced his retirement, interestingly), Monoprice sold it for $99. Its list price is now $129.

The amplifier achieves a high slew rate of 20 V/µs and a gain bandwidth product of 9 MHz, ensuring accurate and responsive audio reproduction across various frequencies. With JFET input technology, ...

An implementation of fractional-order controller suitable for a magnetic levitation system is presented in this work. It is constructed from operational amplifiers as active cells and the main offered ...
