Temperature compensated circuit

Claim 1

A temperature stabilized circuit comprising: (a) circuit means for accepting an input signal; (b) means for establishing a reference voltage comprising a zener diode; (c) a first means for controlling a first current, said first means comprising a first semiconductor, said first semiconductor comprising a plurality of electrodes, said plurality of electrodes being connected in diode configuration, said first means being provided with a reference voltage by said means for establishing a reference voltage, said reference voltage determining a base level of current through said first semiconductor, and said first semiconductor being responsive to a signal from said circuit means; (d) a coupling circuit responsive to a signal from said first semiconductor; (e) second means for controlling a second current to be substantially equal to said first current, said means for controlling second current comprising a second semiconductor, said second semiconductor comprising a plurality of electrodes connected in emitter follower configuration, said second semiconductor having at least one temperature characteristic matched to at least one temperature characteristic of said first semiconductor, and said second semiconductor being coupled to said first semiconductor by said coupling circuit; (f) an output circuit responsive to a signal from said second semiconductor; and (g) means for applying power to the temperature stabilized circuit.
