  • Parabolic current generator
    Patent number: 4028586
    Abstract: A bridge circuit has its input terminals coupled in parallel with an impedance network through which a sawtooth current is passed, the bridge operating to provide an approximate parabolic current through a load coupled to its output terminals. The impedance network includes at least a first impedance coupled in parallel with a series coupled variable second impedance and a third impedance for improving the stability of the parabolic load current.
