Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

[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 ...

This cable tv amplifier circuit is a rf amplifier designed to be quickly installed between two coaxial cables. Both input and output impedances are compatible with 75 Ω cables. The main amplifier si ...

In a signal-conditioning op-amp application there are a number of different approaches to take—what noise and SFDR advantages might one offer over another. In designing an input stage for an analog-to ...
