The low-frequency (1 kHz-25 kHz) negative capacitor demonstrator based on a commercial integrated audio amplifier was designed and prototyped by Prof. Silvio Hrabar and P.h. D. student Boris Okorn. This low-frequency demonstrator generates a large negative capacitance (-1.2 mikroF). Such a large value of negative capacitance enables direct measurements of both voltage and current waveforms in the time-domain, which could help in understanding of the counter-intuitive basic physic. All the measurements clearly show that a negative capacitor could be interpreted as a three-pole generator/sink.
