1) 0805
. 0805. . size code for passives 0.08" long 0.05" wide. Sometimes written as zero eight zero five...
2) unity gain frequency
. unity gain frequency. . the frequency where the voltage gain of an op amp is 1. It indicates the highest usable frequency. It is important because it equals the gainbandwidth product. It is a such frequency of operation for a device where the gain of the component drops to unity.. ...
3) input offset voltage
. input offset voltage. . if you ground both inputs of an op amp, you will still have an output offset voltage. The input offset voltage is defined as the input voltage needed to eliminate the output offset voltage. The cause of input offset voltage is the difference in the Vbe curves of the two input transistors. . ...
4) line voltage
. line voltage. . the voltage from the power line. It has a nominal value of 115V rms. In some places, it may be as low as 105 or as high as 125V rms....
5) component/equipment storage
. component/equipment storage. . There are still to many instances of feeders scattered around the factory floor, stencil screens leaning against shelves and PCBs/components stored in cardboard boxes. . One of the reasons for this problem is that the search for feeder mobiles, reel racks and PCB trolleys can be a difficult task, simply because specifiers are unsure about what makes a good system. To overcome this, Mossman Tebbs` Peter Mossman uses this feature to provide readers with the facts t...
6) smart cards
. smart cards. . DIGITAL television and payperview programmes promise a bonanza not only for broadcasters but for pirates too. The illegal sport of beating the smart card is about to become more popular than ever. . Cloned smart cards are the favourite fraudulent way to watch satellite TV. To make a clone hackers reverseengineer legitimate smart cards which unscramble TV images and copy their circuitry. . TV companies respond by transmitting instructions intended to disable the clones but this ...
7) foldback current limiting
. foldback current limiting. . simple current limiting allows the load current to reach a maximum value while the load voltage is reduced to zero. Foldback current limiting takes this one step further. It allows the current to reach a maximum value. Then further decreases in the load resistance reduce both the load current and the load voltage. The main advantage of foldback limiting is less power dissipation in the pass transistor under shorted-load conditions.. ...
8) lcd
. lcd. . LCD display is one that uses liquid crystals to reflect light (e.g. the numerical display on some pocket calculators).. . . Another definition of lcd:. liquid Crystal Display. ...
9) discrete circuit
. discrete circuit. . a circuit whose components, such as resistors, transistors, etc., are soldered or otherwise connected mechanically.. ...
10) derating factor
. derating factor. . a value that tells you how much to reduce the power rating for each degree above the reference temperature given on the data sheet.. ...
11) liquid solder
. liquid solder. . a tin-lead alloy heated to a liquid point for the electrical termination of devices to a substrate. . ...
12) colpitts oscillator
. colpitts oscillator . . one of the most widely used LC oscillators. It consists of a bipolar transistor or FET and an LC resonant circuit. You can recognize it because it has two capacitors in the tank circuit. They act as a capacitive voltage divider that produces the feedback voltage.. ...
13) pullup resistor
. pullup resistor. . a resistor that the user has to add to an IC device to make it work properly. One end of the pullup resistor is connected to the device, and the other end is connected to the positive supply voltage.. . . Another definition of pullup resistor:. a resistor that the user has to add to an IC device to make it work properly. One end of the pullup resistor is corrected to the device, and the other end is connected to the positive supply voltage.. ...
14) direct addressing
. direct addressing. is where the address specified in the instruction is the address of the location to. be used.. ...
15) surveillance
. surveillance. . lies and electronics. barry fox. Everyday Practical Electronics. August 1996. . The police and security services have an armoury of high tech surveillance equipment. Needless to say they do not like to talk about it. Thermal imaging cameras, which find bodies trapped in rubble after an earthquake or bomb blast, can also monitor movement in a dark room. If a laser is beamed at a window, the reflected light will be modulated by the small vibrations in the glass pane which are c...
16) collector cutoff current
. collector cutoff current. . the small collector current that exists when the base current is zero in a CE connection. Ideally, there should be no collector current. But there is because of the minority carriers and the surface leakage current of the collector diode.. ...
17) h parameters
. h parameters. . an early mathematical method for representing transistor action. Still used on data sheets.. . . ...
18) peak inverse voltage
. peak inverse voltage. . the maximum reverse voltage across a diode in a rectifier circuit.. ...
19) optocoupler
. optocoupler . . a combination of a LED and a photodiode. An input signal to the LED is converted to varying light which is detected by the photodiode. The advantage is very high isolation resistance between the input and output.. ...
20) oscillations
. oscillations. . the death of an amplifier. When an amplifier has positive feedback, it may break into oscillations, which is unwanted high-frequency signal. This signal is unrelated to the amplified input signal. Because of this, oscillations interfere with the desired signal. Oscillations make an amplifier useless. This is why a compensating capacitor is used with an op amp; it prevents the oscillations from occurring.. ...
