A transistor can be operated in three modes, active region, saturation region, and cut-off region. In the active region, the transistor works as an amplifier. As a transistor switch, it operates in two regions and those are Saturation Region (fully-ON) and the Cut-off Region (fully-OFF)...
As an example we will use a typical diode called a pn-junction. This allows us to explain behavior of diodes. Remember,however,that there are other sorts of diodes which are built differently but show the same general behavior.We create a pn-junction by joining together two pieces of ...
A bipolar junction transistor (BJT) contains a highly doped n++ region in the collector adjacent to the base. This region has the effect of reducing noise, such as shot noise and 1/f or flicker noise when the transistor is operating as an amplifier. Preferably, this highly doped region is...
Arduino is an open-source prototyping platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something...
A power amplifier is designed using non-linear elements to linearize the output characteristics of power transistor. It is capable of delivering 15 W. output with <0·5 per cent total distortion and having a bandwidth of 20 c/s. to 15 kc/s. (0·9 db.)....
Using the AVBus protocol it is also possible to control multiple HiFi devices from that device line, for example the PM451 Amplifier. The main purpose of this repo is to serve as documentation. The code in here were my first attempts and I'll consider removing them. ...
Current outputs offer advantages in a number of situations, including analog current-loop signaling (0 mA to 20 mA and 4 mA to 20 mA) in high-noise environments, and level shifting an analog signal across a large potential difference without the use of o
This course introduces basic concepts in Electrical and Computer Engineering,and demonstrates them in the context of real applications.Course topics include transistor,diode and operational amplifier circuits,digital logic gates and power supply operation. D. An introduction to the language of medicine,...
Many applications need an amplifier that delivers a moderate amount of power to a load while maintaining good dc precision, with the size of the load determining the type of circuit required. A precision op amp can drive loads requiring less than 50 mW, and a compound amplifier with a precis...
a transistor amplifier configuration, the IC (max) is the maximum current that can flow through the transistor and VCE (max) is the maximum voltage applied across the device. To work the transistor as an amplifier, a load resistor RC must be connected to the collector. Biasing sets the DC...
