Electronic Devices In the age of IoT, electronics form the ground of development and innovation to reach new heights of scientific maneuver. E.D.C plays the role of a building block in this long and big journey for the development of cutting-edge technology for the future. This blog is a comprehensive summary of what E.D.C is and provides the groundwork for the more complex topics in the field of electronic devices and circuits. What is electronics? The branch of engineering

Electronics domain involves a lot of skills starting from basic device and circuit simulations, to PCB design, micro controllers and a complete IoT system implementation. Hence, for any beginner it is necessary to explore the open source tools and software that can be utilised for skill development, concept building and learning with hands on experience. Octave : For mathematical equations, Matlab basics, numerical computation, plotting graphs, matrices, linear and non linear

Universal Asynchronous Reciever-Transmitter Introduction The transmitter converts parallel data from a controlling device like a CPU into serial form, transmits it in serial to the receiving UART, which then converts the serial data back into parallel data for the receiving device. Data flows from the Tx pin of the transmitter to the Rx pin of the receiver hence only two wires are needed to transmit data. UART transmit data asynchronously, which means there is no clock signal

CMOS Transmission Gate Introduction In electronics, pass transistor logic (PTL) describes several logic families used in the design of integrated circuits. It reduces the count of transistors used to make different logic gates, by eliminating redundant transistors. Transistors are used as switches to pass logic levels between nodes of a circuit, instead of as switches connected directly to supply voltages. This reduces the number of active devices, but has the disadvantage th

Differential Amplifier All operational amplifiers (op-amps) are differential amplifiers because of their input configuration. When the first voltage signal is connected to the input terminal and another voltage signal is connected onto the opposite input terminal then the resultant output voltage is proportional to the difference between the two input voltage signals of V1 and V2. The output voltage can be solved by connecting each i/p intern to 0v ground using a superpositi

Operational Amplifiers Topics to be covered Operational Amplifier Characteristics of Operational Amplifier Op-amp Parameter and Idealized Characteristics. OPAMP applications Operational Amplifier Operational Amplifier Operational amplifiers are linear devices that have all the properties required for nearly ideal DC amplification and are therefore used extensively in signal conditioning, filtering or to perform mathematical operations such as add, subtract, integration, and

The current mirror is a circuit designed to copy a current through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. The current being "copied" can be, and sometimes is, a varying signal current. Conceptually, an ideal current mirror is simply an ideal inverting current amplifier that reverses the current direction as well. Or it can consist of a current-controlled current source (CCC

Introduction to CMOS Stands for "Complementary Metal Oxide Semiconductor." It is a technology used to produce integrated circuits. CMOS circuits are found in several types of electronic components, including microprocessors, batteries, and digital camera image sensors. The "MOS" in CMOS refers to the transistors in a CMOS component, called MOSFETs (metal-oxide semiconductor field-effect transistors). The "metal" part of the name is a bit misleading, as modern MOSFETs often u

The transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Tran

A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Semiconductor diodes were the first semiconductor electronic devices . diodes p – n

A solid substance whose electrical conductivity lies between that of an insulator and a conductor, either due to the addition of impurities or because of temperature effects. When two differently doped regions exist in the same crystal, a semiconductor junction is created. Devices made by semiconductors, notably silicon, are essential components of most electronic circuits. Semiconductor devices can display a range of useful properties, such as passing current more easily in
