| Popis: | A current mode CMOS voltage reference uses a p-channel MOSFET threshold voltage extractor circuit to create a current that is inversely proportional to temperature. This current is summed with a current that is proportional to temperature into a resistor to create a voltage that is, to the first order, temperature independent. The output voltage is scalable by adjusting the size of the summing resistor. The circuit operates over temperature from 0 to 100/spl deg/C with a power supply voltage between 3.3 and 7 V. Experimental results show that over these conditions, the output voltage varies by /spl plusmn/3%. |
