Voltage_reference_with_variable_TC

This circuit uses both sections of an XR-13600 (Fig. 11-1B) to form a voltage reference with variable temperature coefficient. The 100-kΩ potentiometer adjusts the output voltage, which has: 1) a positive TC above 1.2 V, 2) zero TC at about 1.2 V, and 3) a negative TC below 1.2V. This is done by balancing the TC of the A2 transfer function against the complementary TC of D1. EXRA Corporation Databook 1990,p 5-257
