junction. The incoming light produces free electrons and holes. The stronger the light, the greater the number of minority carriers and the larger the reverse current. Optocoupler: LED on the input side and photodiode on the output side. Light from the led hits the photodiode and this sets up a reverse current in the output circuit. 8) How many valence electrons a germanium atom has? 1 2 4 8 How is it called the n-type semiconductor? donor recipient acceptor dipol Ticket No3 ´ 1,2)Collector characteristic(output characteristics) and input characteristic of Bipolar Junction Transistor(BJT) 3)A junction transistor has three doped regions. The bottom is the emitter, middle is base and top is collector.A transistor has two junctions on opposite sides of a thin slaf of semiconductor
I hope it proves useful. ix Introduction Modern electronic systems are increasingly digital: digital microprocessors, digital logic, digital interfaces. Digital logic is easier to design and understand, and it is much more flexible than the equivalent analog circuitry would be. As an example, imagine trying to implement any kind of sophisticated micro- processor with analog parts. Digital electronics lets the PC on your desk execute different programs at different times, perform complex calculations, and communicate via the World Wide Web. While the electronic world is nearly all digital, the real world is not. The temperature in your office is not just hot or cold, but varies over a wide range. You can use a thermometer to determine what the temperature is, but how do you convert the temperature to a digital value for use in a microprocessor- controlled thermostat
