In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

Use this fm antenna amplifier in areas where the signal reception of FM stations is too bad. This circuit is just the right thing to do it. It is designed in such a way that the supply current ...

Onkyo is unveiling two new network streamers and Integrated amplifiers at CES 2026. The Muse Series combine the brand’s ...

Wesgarde is highlighting the Optifuse 641, 642 and 643 mid-amp circuit breakers for large vehicle applications, offering ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...
