  • Protection circuit for an excitation current source
    Patent number: 6072676
    Abstract: A protection circuit for an excitation current source protects against excessive compliance voltage by using a cascode transistor between the current source and an output terminal, and a transistor coupled to the output terminal and to the control lead of the cascode transistor to cause the cascode transistor to turn off if the voltage exceeds a threshold level.
