Design a Simple Constant Current Sink Circuit using Op-Amp Current Source and Current sink are two major terms used in electronics design, these two terms dictate how much current can leave or enter a terminal. For example, the sink and source current of a typical 8051 Microcontroller digital output pin is 1.6mA and 60uA respectively. Meaning the pin can deliver (source) up to 60uA when made High and can receive (sink) up to 1.6mA… |

Design a Voltage Controlled Current Source Circuit using Op-Amp In a voltage-controlled current source circuit, as the name implies, a small amount of voltage across the input will proportionally control the current flow across the output loads. This current source circuit using an op amp is commonly used in electronics to drive current-controlled devices like BJT, SCR, etc. We know that in a BJT, the current flowing through the base of… |

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… |

Current Regulators: Construction, Working and Design Types Just like situations in which we need to regulate the voltage in our designs, there are scenarios where we need to regulate the current that’s being supplied to a particular part of our circuit. Unlike transforming (changing from one voltage level to another), which is usually one of the major reasons for voltage regulation, current regulation is usually about keeping the… |

Current Sensing Techniques using Different Current Sensors Current is a very critical factor in Electronics or Electrical Engineering. In electronics, current can have a bandwidth from few nano-amperes to hundreds of amperes. This range can be much wider in Electrical domain typically to several thousand amperes, especially in Power Grids. There are different methods to sense and measure current inside a circuit or a conductor. In… |
