A simple and inexpensive electronic circuit uses a low-cost pushbutton switch to toggle the electrical power on and off. The circuit replaces a more costly and bulky push-push mechanical switch. The ...

She did not like that beefy switch so I built another one with a “digital” pushbutton switch to toggle the power flow (of course there are electronics in it). I needed to rig up a quick circuit to ...

Mechanical switches can be noisy, generating multiple transient pulses that may cause faulty operation of fast digital circuits. In this design, a pair of MOSFETs are used in a monostable mode to ...

We break down the essential component of modern electronics—the transistor. Transistors are the building blocks behind most ...

Water is usually something you’d want to keep away from electronic circuits, but engineers in Germany have now developed a new concept for water-based switches that are much faster than current ...

3 Analyse and determine the function of basic operational amplifier circuits and design comparators, filters and oscillators using operational amplifier circuits. 4 Discuss the fundamental operating ...

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics ... need for proper circuit protection.
