Negative-resistance connection of 741 opamp is suhable for both AC and DC applications. Requires floating power supply because 0-V terminal floats with respect to both output terminals. For DC use, adjust 10K pot to cancel offset voltage of amplifier. Value of negative resistance is varied with RN or by adjusting ratio of RF to RA. Can be used to make LC circuits operate at subaudio frequencies.-D. A. Miller. Negative Resistor. Wireless World. June 1974. p197.
