Abstract

This article describes a procedure to arrive at a current controlled resistor, based on superconducting films for converting a sinusoidal current waveform of a certain magnitude into a triangular voltage waveform. As an example, it describes a resistor for converting a current of 180 $\mu A$ into a triangular voltage of 22 mV. It is also shown that this resistor can be used to obtain voltage waveforms which are very close to triangular waveforms for input currents in the range 18 to 180 $\mu A$ up to a frequency of 1.0 MHz. Corresponding peak output voltages of the triangular waveform are 1.4 to 22 mV, respectively.
