ABSTRACT:
A negative resistance element having two terminals (11, 12;) a resistor (R1-4) connected in a path between the terminals, and a current mirror arrangement (T1, T2; T3, T4;) responsive to a current flowing into the first terminal (11) to produce a current through the resistor R1-4 in such a direction as to increase the voltage of the second terminal 12 relative to the first terminal 11.
