Introduction to Op Amp (Operational Amplifier) An operational amplifier (op-amp) is a high-gain differential amplifier that amplifies the difference between two input voltages. It is a fundamental building block in analog and mixed-signal circuits, widely used in various applications due to its versatility. How Operational Amplifiers Work Op-amps have two input terminals, inverting (-) and non-inverting (+), and an output terminal. The op-amp amplifies the voltage difference between the two inputs and presents the amplified signal at the output. Ideally, op-amps have infinite input impedance, zero output impedance, and infinite open-loop gain. However, real op-amps have finite values for these…

Introduction to RC Circuit An RC circuit, consisting of a resistor and a capacitor, is a fundamental circuit with numerous applications in various fields. It finds extensive use in timing applications, filtering applications, surge suppression circuits, and more. In timing applications, the RC circuit controls the rise or fall timing of circuit parameters like voltage or current for triggering events. In frequency-domain applications, it serves as a filter, blocking or passing certain frequency bands. RC circuits can also function as differentiators, integrators, or surge suppressors, where the capacitor absorbs surge energy, and the resistance determines the absorption rate. How RC Circuits Work…
Introduction to Peristaltic Pump Peristaltic pumps are positive displacement pumps that transport fluids through a flexible tube by a series of wave-like contractions and relaxations. This unique mechanism eliminates direct contact between the pump components and the fluid, making them ideal for handling shear-sensitive, aggressive, or sterile fluids. How Peristaltic Pumps Work The core components of a peristaltic pump include a flexible tube, a rotor or cam mechanism, and a housing or track. The tube is compressed by the rotor or cam against the housing, creating a series of alternating constrictions and relaxations along the tube’s length. As the rotor or…

Introduction to IR Sensor An infrared (IR) sensor is a device that detects and measures infrared radiation emitted or reflected from objects. IR sensors operate based on the principle that all objects above absolute zero temperature emit infrared energy, which is invisible to the human eye but can be detected by specialized sensors. How IR Sensor Works IR sensors typically consist of two main components: an IR emitter and an IR detector. The emitter, usually an IR LED, emits infrared radiation, which is reflected off the target object. The detector, often a photodiode or pyroelectric sensor, receives the reflected radiation…
