Abstract :
An ultra-high-speed frequency divider using a resonant tunnelling chaos circuit is fabricated, which monolithically integrates a resonant tunnelling diode and a high electron mobility transistor. This frequency divider is based on the long-period behaviour of the nonlinear circuits generating chaos. The various frequency dividing operations are observed at the input frequency of 50 GHz. Chaotic operation is also observed
