发明名称 Methods and apparatus to produce fully isolated NPN-based bandgap reference
摘要 Generating a bandgap reference by generating a first current in a first circuit and a second current in a second circuit, a control circuit forcing the first and second currents to have a first magnitude proportional-to-temperature. Generating a third current in a third circuit having a second magnitude based on a first voltage associated with the first circuit, the second magnitude being complementary-to-temperature. Adding the first and second magnitudes in a fourth circuit to form a third magnitude substantially constant over change in temperature, the fourth circuit generating a fourth current having the third magnitude. Adding the first and second magnitudes to generate a fifth current having the first magnitude in a fifth circuit and a sixth current having the second magnitude in a sixth circuit, the fifth and sixth circuits sinking current from the fourth circuit.
