Abstract
A current generator (8) is provided. A voltage delta circuit (15) is operable to generate a voltage difference between a first circuit node (NODE 1) and a second circuit node (NODE 2) and is operable to generate a first current (I.sub.1) and a second current (I.sub.2). A junction field-effect-transistor (14) is coupled to the first circuit node (NODE 1) and the second circuit node (NODE 2). The junction field-effect-transistor (14) operates in a resistive region to stabilize a temperature characteristic of the first current (I.sub.1) and the second current (I.sub.2). A current mirror circuit (19) coupled to the voltage delta circuit (15), the current mirror circuit (19) operable to receive the first current (I.sub.1) and the second current (I.sub.2).
