Abstract
A current reference for providing a stable current output across a range of temperatures and input power supply voltages by summing signals from a first and second current generation subcircuits which generate temperature dependent signals having in inverse relationship. The first current generation subcircuit includes two NMOS transistors and a resistor and has a negative thermal coefficient. The second current generation subcircuit includes two bipolar transistors and a resistor and has a positive thermal coefficient.
