  A dual realization of Chuas chaotic oscillator is proposed using
current-controlled nonlinear resistors, one linear resistor, one capacitor and
two inductors. Two problems are solved. First, unit rescaling is necessary when
transforming the standard chaotic equations into circuit equations to ensure
that the current units are milliamperes. In addition, the connection and
parameters of two current-controlled nonlinear resistors are set to build the
required volt-ampere characteristics. The inductor currents show the classical
characteristics of being sensitive to the circuit parameters and initial
conditions. In addition, experimental verification is performed to demonstrate
the feasibility of the circuit. Chuas dual circuit exhibits rich dynamic
chaotic features and might bring new applications due to chaotic currents.
