Hartley Oscillator In simple terms, the oscillator is a circuit which converts DC power from the supply source to the AC power to the Load. Oscillator system is built using both active and passive components and it is used for the production of sinusoidal or any other repetitive waveforms at the output without any application of an external input signal. We discussed few oscillators in our… |

Understanding Pulse width Modulation (PWM) in Atmega16/32 AVR Microcontrollers Pulse Width Modulation (PWM) is a powerful technique where width of the pulse is changed by keeping the frequency constant. The technique is used in many control systems today. The application of PWM is not limited and it is used in wide range of applications such as motor speed control, measurement, power control and communication etc. In PWM technique, one can easily… |

Colpitts Oscillator An oscillator is a mechanical or electronic construction which produces oscillation depending on few variables. We all have devices which need oscillators like a traditional clock or a wristwatch. Various types of metal detectors, computers where microcontroller and microprocessors are involved use oscillators, especially electronics oscillator which produces periodic… |

Sawtooth Waveform Generator Circuit In electronics, waveforms are mostly plotted against voltage and time. The frequency and amplitude of the signal can vary according to the circuit. There are many types of waveforms, like sine wave, square wave, triangular wave, ramp wave, sawtooth wave etc. We have already designed sine wave and square wave generator circuit. Now, in this tutorial we will show you, how to… |

Differential Amplifier or Voltage Subtractor Circuit Op-Amps were originally developed for Analog mathematical calculations, since then today they have proved to be useful in many design applications. As my professor ones rightly said, op-amps are arithmetic voltage calculators, they can perform addition of two given voltage values using Summing Amplifier circuit and difference between two voltage values using a Differential… |

Classes of Power Amplifiers In electronics, Amplifier is the most commonly used circuit device with huge application possibilities. In Audio related electronics pre-amplifier and power amplifiers are two different types of amplifier systems which are used for sound amplification related purposes. But, other than this application-specific purpose, there are huge differences in various types of… |

ARM7-LPC2148 PWM Tutorial: Controlling Brightness of LED As we know microcontrollers take analog input from analog sensors and use ADC (Analog to Digital converter) to process those signals. But what if a microcontroller want to produce an analog signal to control analog operated devices like a Servo motor, DC motor etc? Microcontrollers don’t produce output voltage like 1V, 5V instead they use a technique called PWM for operating… |

Peak Detector Circuit Peak Detector Circuit is used to find the peak amplitude in a rapidly changing waveform. Peak detectors are generally used in the sound measuring applications to find the maximum level of sound in a particular area or place, that helps in determining the maximum loudness level in that place. So, like this there are number of applications where a Peak Detector Circuit is used… |

New ADC and DAC ICs to Reduce System Footprint and Improve Performance Texas Instruments introduced four tiny precision data converters, enabling designers to add more intelligence and functionality, while shrinking system board space. The DAC80508 and DAC70508 are eight-channel precision digital-to-analog converters (DACs) that provide true 16- and 14-bit resolution, respectively. The ADS122C04 and ADS122U04 are 24-bit precision analog-to-… |

How to measure value of Inductor or Capacitor using Oscilloscope – Resonant Frequency Method Resistors, Inductors and Capacitors are the most commonly used passive components in almost every electronics circuit. Out of these three the value of resistors and capacitors are commonly marked on top of it either as resistor colour code or as numeric marking. Also the resistance and capacitance can also be measured using normal Multimeter. But most of the inductors,… |
