If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...

This article will address a historical perspective on a common type of negative feedback amplifier topology used for amplifying standard definition video signals (i.e., composite video). With the ...

Design analysis of the K2-W Vacuum Tube Op Amp’s design and operation reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. Op amps played a critical role ...

Modeling the performance of an analog device with SPICE is one of the standard techniques used by circuit designers to perform initial characterization and performance analysis before putting together ...

ROHM has introduced the TLRx728 and BD728x series. These CMOS op amps are designed to balance versatility and high performance, specifically targeting the need for faster speed, better precision, and ...

In an earlier blog (Comparing Op-Amp & Video Amp Topologies, Part 1), we examined the bandwidth and phase requirements for processing video. In the most recent blog, we looked at the AC and DC ...
