Design and Build a Simple Bistable Multivibrator Circuit Using Op-amp The bistable multivibrator is one of those basic circuits which you might have learnt about in your high school or college, and you probably have built one with 555 timers or with discrete components like OP-amp, transistors, or resistors. These circuits are often viewed as simple educational circuits, but not so surprising they are also used in practical designs… |

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… |

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… |
