Abstract: Electrical circuits are described that can be connected in series with a voltage source and a load in the same manner as a field-effect current-regulator diode to supply the load with a constant current having a temperature coefficient below 0.01%/*C. from 0* to 60* C. at current levels as low as 10 microamperes and having a voltage coefficient below 0.1%/volt from 5 to 12 volts. Very precise temperature compensation can be achieved at the desired current by adjustment of two resistors in these circuits.
