The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...
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 ...
One part wants 3.3V logic. Another wants 5V. What do you do? Over on the [Playduino] YouTube channel, there’s a recent video running us through a not-so-recent concern: various approaches to ...
Any typical digital design style with CMOS uses complementary pairs of p-type and n-type MOSFETs for logic functions implementation. Naturally, CMOS always ought to provide INVERTED outputs like ...
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 ...
Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...
