| Electronic circuits have at least one thing in common: they need power to operate. The power supply described in this article has bee...
| Following the detailed description of the preamplifier in last month's installment, this second and final part of the article deals with t...
| It is well known that the frequency of a crystal oscillator depends to some degree on the ambient temperature. AIthough this is often...
| Electronic circuits that draw a current of more than a few milliamperes should preferably not be powered by a battery: most are, therefore,...
| If you're looking for an audio amplifier that produces a lot of power using an absolute minimum number of components. this one is for yo...
| In certain applications it may be desirable, in order to limit unnecessary power losses, to have the use of a diode with a forward voltag...
| The circuit shown in here has been designed to protect (expensive) high-power resistors against overheating. Very high power resistors (...
| A symmetrical power supply may be designed from two standard opamps, but it can only provide a small current (of the order of a few mA).
| A stabilized power supply unit with current limiting is described that not only provides but also accepts power. This property is indisp...
