Using this easy transistor tester circuit, find out whether a given transistor is good or bad before soldering it. You can also identify npn and pnp types easily. The tester gives LED indication of the pin-outs as well as...
There are many different audio power amplifier ICs to choose from, but designing an audio power amplifier using an operational amplifier (op-amp) and bipolar transistors is quite advantageous. Compared to audio ICs, power transistors are easy to replace in case...
To design a single stage transistor amplifier, many formulae are required to calculate the various parameters such as values of resistors, coupling capacitor, bypass capacitor, power consumption, current flowing through different components and others. A good amount of time...
It is a well-known fact that the highly remarkable supercomputers are power-hungry and staggeringly inefficient machines. In the meantime, our brains consist of about 86 billion neurons that are connected by synapses that not only establish myriad logic circuits,...

These days there a lot of audio power amplifiers in integrated circuits (ICs). But it is still interesting to produce audio power amplifiers with operational amplifiers (OAs) and with output power bipolar transistors. Some of the reasons for that...
Transistors are the basic building blocks of integrated circuits (IC). Every electronic gadget you can possibly imagine today uses transistors. The development started off with vacuum tubes and lead to the transistor as the BJT we see today. A bipolar junction...
Electronics revolution has been a very interesting one. You have lightning fast connectivity, crystal clear displays, blazing fast processors, all in a handheld device. A major part in the device however has been the silicon. With recent mishaps, resulting...
STMicroelectronics recently announced power semiconductors for Hybrid and Electric Vehicles (EVs) with a timetable for qualification to the automotive quality standard AEC-Q101. In EVs and hybrids, where better electrical efficiency means greater mileage, the new silicon-carbide (SiC) technology enables efficient...
Transistor fabrication is a highly complex process, requiring high-temperature, high-vacuum equipment. In another step in combining consumer electronics and nanotechnology, University of Pennsylvania engineers have shown a new approach for making transistors: sequentially depositing their components in the form...
