Current Mirror Circuit (Part 1): Introduction, Characteristics and Construction The Current Mirror is a widely popular technique for monolithic IC design. In this technique, the circuit is designed in such a way that it copies the current through one active device to another active device with current control feature. In this, the current is flowing through one device can be copied into another device but in inverting form. If the current of the first… |

Simple H-Bridge Motor Driver Circuit using MOSFET At the outset, driving a motor might seem like an easy task – just hook the motor up to the appropriate voltage rail and it will start rotating. But this is not the perfect way to drive a motor, especially when there are other components involved in the circuit. Here, we will discuss one of the most commonly used and efficient ways to drive DC motors, the H-Bridge circuit.… |

What is MOSFET: Its Construction, Types and Working MOSFET is basically a transistor which uses field effect. MOSFET stands for Metal Oxide Field Effect Transistor, which has a gate. The gate voltage determines the conductivity of the device. Depending on this gate voltage we can change the conductivity and thus we can use it as a switch or as an amplifier like we use Transistor as a switch or as an amplifier. … |

Single Phase Half Bridge and Full Bridge Inverter using MATLAB Alternating Current (AC) power supply is used for almost all the residential, commercial and industrial needs. But the biggest issue with AC is that it cannot be stored for future use. So AC is converted into DC and then DC is stored in batteries and ultra-capacitors. And now whenever AC is needed, DC is again converted into AC to run the AC based… |
