Temperature compensated reference current generator
 A temperature compensated resistance current generator. The generator provides temperature compensated reference current in a digital CMOS environment where resistors with positive temperature coefficients are not available, and where temperature coefficients are large. The current generator has two current sources and a subtraction circuit which subtracts the current from one current source from the current from the other current source to create a primary current. A proportionality circuit multiplies the primary current by a constant to produce the generator output.
