... Base-emitter voltage variation with temperature is an important consideration, especially in power circuits, because in those the temperature of the transistors tends to increase by a considerable amount. The circuit most-commonly used to compensate for that is shown in Fig. 6. Diode D is placed int ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
