Abstract:
1. A current generator, comprising: a thermistor configured to receive an input current; a reference resistor having a resistance substantially equal to a resistance of said thermistor at a reference temperature; a current mirror configured to generate a mirrored current proportional to said input current; a feedback circuit having inputs electrically coupled to the thermistor and reference resistor, the feedback circuit being configured to generate an output compensation current proportional to a difference between voltages on said reference resistor and on said thermistor; and a first adder having an input configured to be fed back the output compensation current from the feedback circuit, and an output electrically coupled to one of the inputs of the feedback circuit, the first adder being configured to apply to said reference resistor a difference current corresponding to a difference between said mirrored current and said output compensation current.
