Detailed Solution
Download Solution PDFDarlington Pair: CC – CC
- A Darlington pair is a two-transistor circuit with the emitter of one transistor is connected to the base of another transistor, while both collector terminals are connected to the common terminal.
- It has high current gain β; (equal to the product of current gain of individual transistors)
- It can be regarded as a single transistor with a high value of β and hence very high input resistance
- It also has high input impedance and low output impedance
- The current gain of a Darlington pair in common emitter configuration is approximately β2
- It also has high input impedance and low output impedance
The symbolic diagram of the Darlington pair is shown below
