You can implement many fundamental building-block circuits such as a difference amplifier (DA) or instrumentation amplifier (IA) using discrete or integrated components. Design engineers often debate ...

The transfer function of this amplifier is: With R1 = R3 and R2 = R4, Equation 1 simplifies to This simplification can be a quick way to approximate the expected signal, but those resistors are never ...

Why discretes tend to win out over ICs when it comes to designing ‘folded cascode’ charge amplifiers. By Tolga Aydemir Integrated circuits (ICs) are vital in helping to reduce the cost, size and ...

Exquisitely tuned by the Marantz Sound Master, the MODEL 30 integrated amplifier features a master-curated Marantz HDAM and a fully discrete design for luxurious Hi-Fi purity. The new MODEL 30 ...

We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and ...

High-side current-sense amplifiers (CSAs) are principally used for monitoring the current from a positive supply rail. However, applications like ISDN and telecom power supplies require CSAs that ...

NAD, the highly regarded manufacturer of high-performance audio components, introduces the M3 Dual Mono Integrated Amplifier, one of the first four new components in the new Masters Series during the ...

[Ynze] has built an audio amplifier that looks and sounds great. His amplifier uses a National Instruments (now TI) LM3886 Overture series 68 Watt power amp. The LM3886 places [Ynze’s] amp squarely in ...
