In order to have interference with the outside world using microcontrollers, it can be done through pins. These pins act as physical points for an integrated circuit where a PCB connection can be established. Each pin has its own circuitry, and it is configured to pins to allow interference with various kinds of circuits. And the most important point is to select the appropriate pin configuration in the design of an embedded system. Today, this article explains open-drain output configuration, … [Read more...]

A three-terminal semiconductor device like UJT (uni-junction transistor) exhibits different characteristics like switching and negative resistance to using as a relaxation oscillator within phase control applications. This type of transistor can also be used in timing, trigger generator, and gate pulse applications. Similar to diodes, the construction of UJT can be done by using separate P-type & N-type semiconductor materials to form a single PN junction in the main N-type conducting … [Read more...]

The MOSFET is an important element in embedded system design which is used to control the loads as per the requirement. Many of electronic projects developed using MOSFET such as light intensity control, motor control and max generator applications. The MOSFET is a high voltage controlling device provides some key features for circuit designers in terms of their overall performance. This article provides information about different types of MOSFET applications. … [Read more...]

Transistors are developed in the year 1947 by the physicists of America named John Bardeen. Before the use of transistors, vacuum tubes used for the purpose to control electronic signals. But the complexity of designing vacuum tubes, more amount of power consumption paved the way for the inception of transistors in modern electronics. The transistors are one of the most frequently used semiconductors utilized in the applications of switching and amplification. To make the transistor function … [Read more...]
