Abstract
A circuit for stabilizing an electric current includes a constant voltage supplying circuit configured to supply a constant voltage, and a current generating circuit coupled to the constant voltage supplying circuit to generate an electric current based on a predetermined voltage responsive to the constant voltage and to adjust a current amount of the electric current to a predetermined amount by feedback control based on comparison of the predetermined voltage with a voltage appearing across a predetermined resistance responsive to the electric current.
