The behavior of two frequency divider circuits using negative differential resistance (NDR) circuit is studied. This NDR circuit is made of three resistors (R) and two bipolar-junction-transistor (BJT) devices. It can show the NDR characteristic in its current-voltage curve by suitably designing the resistances. We discuss a dynamic frequency divider, which is made of a R-BJT-NDR circuit, an inductor, and a capacitor. This frequency divider circuit is based on the long-period behavior of the nonlinear NDR circuits generating chaos. It demonstrates the period-adding sequences which appear in its bifurcation diagram to perform the frequency division. We investigate the effects of the input signal frequency on the operation. The results show that the dividing ratio can be selected by changing the input frequency. We also discuss the effect of inputting different types of signals with the same frequency on the operation of this frequency divider. The results show that the input signal distortion has a negligible influence on the frequency divider state.
