12V 1A Power Supply Circuit Design using VIPer22A Switched-mode power supply circuits (SMPS) are most often required in many electronic designs to convert the AC mains voltage to a suitable level of DC voltage for the device to operate. This type of AC-DC converter takes in the 230V/110V AC mains voltage as input and converts it to low-level DC voltage by switching it, hence the name switch-mode power supply. We have… |

Arduino Sleep Modes and How to use them to Save the Power Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem, almost every controller comes with an Arduino sleep mode, which helps developers to design electronic gadgets for optimal power consumption. Sleep mode puts the device in power-saving mode by turning off the unused module. Whether you… |

What is JFET: Its Construction, Working and Biasing Techniques JFET is a Junction gate field-effect transistor. A normal transistor is a current-controlled device which needs current for biasing, whereas a JFET is a voltage-controlled device. Similar to MOSFETs, as we have seen in our previous tutorial, JFET has three terminals: Gate, Drain, and Source. JFET is an essential component for precision-level voltage… |

Voltage Controlled Oscillator (VCO) Most of the consumer electronic devices around us, such as mobile phones, TVs, Radios, and MP3 players, are a combination of Digital and Analogue electronics. Wherever wireless transmission/reception, or audio signals are involved in an electronic design, we will need periodic oscillating electronic signals. These signals are called Oscillating signals and are very useful in… |

Passive High Pass Filter Previously, we discussed the Passive Low Pass Filter; now it is time to look into the passive high pass filter. A passive high pass filter is an electronic circuit that allows high-frequency signals to pass while blocking low frequencies below a predetermined cutoff point. Same as before, if you look into the name, it shows “Passive”, “High… |

Interfacing ADC0808 with 8051 Microcontroller ADC is the Analog to Digital converter, which converts analog data into digital format; usually, it is used to convert analog voltage into digital format. Analog signal has an infinite no of values, like a sine wave or our speech, ADC converts them into particular levels or states, which can be measured in numbers as a physical quantity. Instead of continuous conversion, ADC… |
