How to Build a DIY Oscilloscope using Arduino UNO Minima? When working with electronics, a multimeter can tell you the voltage at a particular moment, but it cannot show you how that voltage changes over time. To observe these changes and understand what's happening inside a circuit, we need an oscilloscope. But instead of investing in a dedicated instrument, what if we could build a simple one ourselves using a… |

Voltage to Frequency Converter using AD654 A voltage-to-frequency converter (VFC) is an oscillator that outputs a square-wave, whose frequency is linearly proportional to its input voltage. The output square wave can be directly fed to a digital pin of a microcontroller to accurately measure the DC input voltage, which means the input voltage can be measured using 8051 or any other microcontroller which does not have… |

How to build an Analog Mixer - Additive Mixer and Multiplicative Mixer A mixer is a special type of electronic circuit that combines two signals (periodically repeating waveforms). Mixers find a lot of use in audio and RF systems and rarely used as simple analog ‘computers’. There are two types of Analog Audio Mixers - Additive Mixers and Multiplicative Mixers. 1. Additive Mixers Like their name suggests, additive mixers simply add… |

Diode Clamper Circuits Previously we learned about Clipper Circuits, which are used to clip off the positive or negative part of the Alternating waveform. Today we will learn about Clamper circuits which are used to clamp the DC level of the output signal without distorting the waveform i.e. they are Level Shifter circuits. It can be designed using capacitor, diode and resistor. The… |

Capacitor ESR Meter using Oscilloscope Capacitors seem all fine till you get to the point where a power supply fails or refuses to perform optimally. And if the problem is noise, there is a simple fix, you just add more capacitors. But that does not solve it. What could be wrong? The problem arises from the naïve assumption that capacitors (to a large extent) are ‘ideal’ devices, while… |

Diode Clipper Circuits: Design & Demonstration As the name suggests, Clipper circuit is used to “clip” a portion of input signal without distorting the remaining part of the waveform. It is a wave shaping circuit. This can be very useful in the circuits where the input signal attains a higher value of voltage than the expected one. These circuits can be implemented in various ways according to the configuration or… |

How to Measure Current with an Oscilloscope Measuring current is a simple task – all you need to do is hook up a multimeter to the circuit you want to measure and the meter gives you a clean value to use. Sometimes you can’t really ‘open up’ the circuit to put a multimeter in series with what you want to measure. This is solved quite simply too – you just need to measure the voltage across a known resistance in the… |

Charge Pump Circuit - Getting Higher Voltage from Low Voltage Source The situation is simple – you have a low voltage supply rail, say 3.3V, and you want to power something that needs 5V. This is a tough call, especially if batteries are involved. The only apparent way is a switch mode converter, more specifically a boost converter. This is where we hit a roadblock – boost converters are inefficient at low powers,… |
