The process of circuit design can cover systems ranging from national power grids all the way down to the individual transistors within an integrated circuit. For simple circuits the design process ...

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 ...

When I was recently debugging a design, I discovered that a short circuit existed from a ground plane to a power plane. I did not have access to a milliohmmeter or an equivalent tester for locating ...

With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

All circuits, analog or digital, have characteristics dependent on the values of their component parts. Invariably, these parts are non-ideal in many ways. Even their most fundamental characteristics, ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.
