1. A circuit coupled to a voltage source and a current source means, said circuit limiting voltage spikes across two input circuit lines of a voltage spike producing circuit, said circuit comprising:

  • a capacitor having a first end connected to said first input circuit line, said first lead of said voltage source and a first lead of said current source means;

    a resistor having a first end connected to a second end of said capacitor and having a second end connected to a second lead of said voltage source and a second lead of said current source means; and

    a diode having an anode connected to said second end of said capacitor and having a cathode connected to said second input circuit line and a third lead of said current source means, wherein excess current flow is from said first input circuit line through said capacitor and diode to said second input circuit line and wherein voltage across the two circuit lines is clamped to approximately the voltage of said voltage source.
