Electronic circuit for producing a reference current independent of temperature and supply voltage |
摘要 |
A current reference circuit comprises a positive temperature coefficient circuit and a negative temperature coefficient circuit, the temperature coefficients of which can be adjusted to give a temperature independent output current. The base of a transistor in the positive temperature coefficient circuit is connected to the base of a transistor in the negative temperature coefficient circuit to bias it.
