What we have learnt
- Current mirrors are essential for generating multiple references from a single current reference.
- The MOSFET version of a current mirror operates similarly to its BJT counterpart.
- Understanding the characteristics of current mirrors is crucial for effective circuit design.
Key Concepts
- -- Current Mirror
- A circuit that copies the current from one branch to another, maintaining the same current flow.
- -- MOSFET
- A type of transistor used for switching or amplifying signals in electrical circuits.
- -- BJT
- Bipolar Junction Transistor, a type of transistor that uses both electron and hole charge carriers.
- -- Reference Current
- A stable current used as a basis for other current values in electronic circuits.
