My caller last week was in a real bind. The design was almost done and he had run out of room. He needed help. The system needed a comparator function and the circuit board was full. After going over ...

In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

If you’re a child of the ’80s or ’90s, chances are you’ve spent hours tracing out intricate patterns using the pens and gears of a Spirograph kit. Simple as those parts may be, they’re actually a very ...

So, you have selected an MCU with an analog-to-digital converter (ADC) and analog comparator peripherals for your cost-sensitive application. You then realize that your sensor signal needs to be ...

Fig 1. The standard Howland Current Pump (HCP) is a current source that can generate both positive and negative current. Fig 2. Adding a boost circuit to an HCP design allows for higher output current ...

Sometimes, there are too many choices in this world. My benchtop function generator can output a sine, square, or saw wave anywhere from 0.01 Hz up to 60 MHz? Way too many choices. At least, that’s ...
