RTD/CMOS nanoelectronic circuits: thin-film InP-based resonant tunneling diodes integrated with CMOS circuits

Comparison of Bistable Circuits Based on Resonant-Tunneling Diodes

Using computer-aided circuit simulation, the speed of RTD-based bistable circuits has been evaluated in terms of device parameters, such as the transistor’s fT and fmax, and circuit parameters, such as sizing. Two topologies studied in this work are: 1) monostable-to-bistable transition logic element (MOBILE), and 2) quantum bistable logic circuit (QBL). The transistors studied in this paper ar...

Multi-GHz MVL Circuits Using Compound-Semiconductor Resonant-Tunneling Diodes

Compound semiconductor devices are commonly used in today’s wideband communications systems. In particular, they are indispensable to build the front-end stage, which is required to process high-frequency signals. Introduction of resonant-tunneling diodes (RTDs) to the front end would result in even better system performance. In the long term, such efforts are expected to pave the way for post-...

Photo-Detectors Integrated with Resonant Tunneling Diodes

We report on photo-detectors consisting of an optical waveguide that incorporates a resonant tunneling diode (RTD). Operating at wavelengths around 1.55 μm in the optical communications C band we achieve maximum sensitivities of around 0.29 A/W which is dependent on the bias voltage. This is due to the nature of RTD nonlinear current-voltage characteristic that has a negative differential resis...
