Positive Feedback in Electronic Circuits
https://www.electronics-lab.com/article/the-positive-feedback-in-electronics/
Introduction While negative feedback controls and corrects the behavior of a system, positive feedback encourages and strengthens the behavior of the system. For this reason, it is also known as regenerative feedback. Positive feedback generally occurs when the fed-back signal is in phase with the input signal, and it causes the magnitude of the input signal […]
Analog to Digital Converter (ADC)
https://www.electronics-lab.com/article/analog-to-digital-converter-adc/
Analog to Digital Converter An analog-to-digital converter (ADC) is an electronic circuit that is used to convert a real-world signal into a digital or binary code. Real-world signals are usually taken from a sensory system which are generally analog in nature and represent instantaneous value of the measured entity. The sensory system may represent any […]
Digital Comparator
https://www.electronics-lab.com/article/digital-comparator/
Digital Comparator A Digital Comparator is another type of combinational logic circuit that is used to compare binary digits. It is a very useful logic circuit used in many digital systems to compare values of digital inputs. A binary comparator can be built using only Standard or Basic logic gates i.e. AND, OR, and NOT […]
Operational Amplifier Basics
https://www.electronics-lab.com/article/operational-amplifier-basics/
Introduction This tutorial is an introduction to the Operational Amplifiers, also known as op-amps. The fundamental goal of op-amps is to amplify a voltage difference and it is the reason why we also describe them as differential amplifiers. Op-amps have been invented the exact same year as the transistors (1947) and they were originally designed […]
Use a Comparator or Op-Amp to Simplify Light Dependent Resistor Output
https://www.electronics-lab.com/use-comparator-op-amp-simplify-light-dependent-resistor-output/
If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In the dark, these devices produce resistances in the megohm range, and can fall to hundreds of ohms […]
Op amps, comparators – smaller than ever

Aimee Kalnoskas @ eeworldonline.com discuss about TI’s tiny OPAMP and comparators. Texas Instruments introduced the industry’s smallest operational amplifier and low-power comparators at 0.64 mm2. As the first amplifiers in the compact X2SON package, the TLV9061 op amp and TLV7011 family of comparators enable engineers to reduce their system size and cost, while maintaining high […]
Simple nanosecond-width pulse generator provides high performance
https://www.electronics-lab.com/simple-nanosecond-width-pulse-generator-provides-high-performance/
by Jim Williams @ edn.com If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The circuit of Figure 1, built around a quad high-speed comparator and a high-speed gate, has settable 0- to 10 ns output […]
Introduction to OPAMPs and Applications
https://www.electronics-lab.com/introduction-to-opamps-and-applications/
Operational amplifiers (OPAMPs) are high performance differential amplifiers in integrated form that can be used in many different ways. A typical OPAMP has a non-inverting input, an inverting input, two dc power pins, one output pin and a few other fine-tuning pins. On the following image you can see a typical diagram of an operational […]
