BJT Widlar Current Source Design 🌟 Calculations & SPICE Simulations 💡 Example 4

In this video, we will discuss the design of a Widlar current source. This current source is mainly used to create very small currents, on the order several microamperes.In order to get the same low current with current mirror or Wilson current source, you will need to use a large resistor, which is not always practical, especially in IC design. We will determine the required reference current and the component value for a required load current. We will also do parameter sweep analysis and discuss the effect of the change in load voltage. We also verify our calculations using simulations in TINA-TI SPICE. We follow a logical procedure and provide the solutions step by step such that it clear for you what and why we carry out a specific action. 👉 Playlist Transistor Circuits:    • Transistor Circuits   👉 Playlist Analog Electronics:    • Analog Electronics   ⭐ If you have questions or comments, please let me know.
