Is there a way to minimize the temperature dependence of VBE. I am trying to design a BJT switch, that will turn on at a particular voltage(43v). ckt attached. The base sees 0.65v when Vcc is 43v or more (resistor divider bias). This turns on the BJT. It should be off when Vcc is 42V or less. I tried adding Re, but that didn't help much during simulation.
