![Graphic][1] It was with a heavy heart that I heard of the tragic death of my old mate and Brother-in-Arms, Peter Roberts. Diagnosed with metastatic lung cancer in January 2017, he knew the end was nigh and another surgical giant has gone home and he will be sorely missed.

Proceedings of the 2016 ACM Conference on Designing Interactive Systems, 2016
This paper argues that comics are a powerful and valuable medium for representing research through design. We review different formats for representing design including the academic paper, the photo-essay and the annotated portfolio. We argue that the comic book form can be better suited to representing various aspects of the design process including ...

A Sub-THz RTD-pair Oscillator with Enhanced RF Output Power Characteristics [PDF]
, 2019 This work shows an RTD-pair oscillator for enhanced RF output power in a sub-THz frequency range. In order to increase the output power of the RTD oscillator, the RTD-pair configuration based on the improved RTD device structure has been employed.

RTD-based compact programmable gates
2004 IEEE International Joint Conference on Neural Networks (IEEE Cat. No.04CH37541), 2005This work presents novel and extremely compact implementations of programmable gates on the basis of the multi-threshold threshold gate concept. The circuit consists of resonant tunnelling diodes (RTDs) and heterostructure field effect transistors (HFETs) and its operating principle is based on the controlled quenching of clocked series-connected RTDs.

RTD characteristics for micro-thermal sensors
Microelectronics Journal, 2008The physical and electrical characteristics of MgO (medium layer) and Pt (sensor material) thin films deposited by a reactive RF sputtering method and a magnetron sputtering method, respectively, were analyzed as a function of the annealing temperature and time by using a four-point probe, SEM, and XRD.

Analysis of frequency divider RTD circuits
IEEE Transactions on Circuits and Systems I: Regular Papers, 2005The behavior of a novel circuit topology able to implement a frequency divider is studied. This circuit is composed of a resonant tunnelling diode (RTD), an inductor, and a capacitor, so it exhibits a very high operating frequency and low power consumption.

Circuits and devices with integrated VFETs and RTDs
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003We have realised a new technology for the integration of VFETs and RTDs. For these tunnelling transistors (so called resonant tunnelling permeable base transistors) we have developed large signal models which have been implemented in a Cadence simulation environment. The DC I-V characteristics are reproduced to a very high degree in these models.

HYPERCHAOS IN RTD-BASED CELLULAR NEURAL NETWORKS
International Journal of Bifurcation and Chaos, 2008In this paper, a hyperchaotic RTD-based cellular neural network is proposed and its hyperchaotic dynamics is demonstrated. The Lyapunov exponents spectrum is presented, and some typical Lyapunov exponents are calculated in a range of parameters. Several important phase portraits are presented as well.

Current-feedback linearization technique for RTDs
ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003A very simple yet accurate linearization technique for RTDs is described. Correction of the intrinsic parabolic curvature of this type of temperature transducer is performed by changing the amplitude of the excitation current as the temperature varies.
