Final answer:
A temperature independent voltage can be achieved using a bipolar junction transistor (BJT) with the principle of temperature compensation. The BJT can be biased in such a way that the voltage across the transistor remains constant regardless of changes in temperature.
Step-by-step explanation:
Temperature Independent Voltage using BJT
A temperature independent voltage can be achieved using a bipolar junction transistor (BJT) with the principle of temperature compensation. The BJT can be biased in such a way that the voltage across the transistor remains constant regardless of changes in temperature.
Principle of Temperature Compensation
The temperature compensation principle involves choosing appropriate biasing conditions for the BJT to counteract the temperature effects on its characteristics. This can be achieved by selecting the appropriate bias current, bias voltage, and resistor values in the transistor circuit.
For example, by using a feedback circuit that adjusts the bias voltage based on the temperature, the variations in the base-emitter voltage of the transistor can be compensated, resulting in a temperature-independent voltage output.
