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 ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

Usually targeted at audio applications, these circuit blocks find homes in all types of designs. Here’s a quick study of their operation and properties. Two of the most often used amplifier building ...

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 ...

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., ...

Using a multi-shunt-based current-monitoring circuit with a 50-MHz op amp delivers an overcurrent detection response time of ...

An anti-log amplifier design with a temperature-compensation network built around a nearly linear PTC thermistor.

According to ROHM, its ultra-compact TLR1901GXZ CMOS op amp is the industry’s lowest operating circuit current. The op amp is ...

We talk to engineer Taresh Vadgama, who has spent over 40 years with NAD, and take a deep dive into the legendary budget ...
