1-12-1993 | 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).

1-10-1993 | There is little to say about the true r.m.s. converter. The circuit diagram shows a standard application of the AD736JN, connected to a n...

1-07-1993 | Often only a single power supply is available for an opamp circuit. Since such circuits normally require a double supply, this means that...

1-05-1993 | A stabilized power supply unit with current limiting is described that not only provides but also accepts power. This property is indisp...

1-12-1992 | The type NH -02 humidily sensor from Figaro consists of a capacitive humidity sensor, Zg, in series with a thermistor, Zt on an aluminium...

1-12-1992 | Integrated voltage regulators LM317 and LM337 enable a simple, regulated, symmetrical power supply as shown in the diagram to be designed....

1-07-1992 | This Iittle circuit enables you to measure the so-called dynamic response of a d.c. power supply. A power MOSFET, T1, is used to switch...

1-07-1992 | Model aircraft tend to be realistic reproductions of the real thing. That means, among others, that starting the petrol engine must be d...

1-07-1992 | If a d.c. coupled output amplifier breaks down during operation, the loudspeakers, particularly the bass units, are at risk. The bass par...

1-07-1992 | The best known alternatives to a 'quick and dirty' power supply are tbe three-pin flxed voltage regulator and the zener-plus-transistor...
