A current mirror (CM) based on self cascode arrangement, useful for low voltage analog and mixed mode circuit is proposed. The CM uses 4 MOSFETs, has high input and output swing, operating at ± 0.5 V supply. Pspice simulations confirm the high performance of this CM having a bandwidth of 2.1 GHz. Resistive and capacitive compensations result in about threefold bandwidth increase to 6.1 GHz.

Increasing numbers of analog components in today’s systems necessitate system level test composition methods that utilize onchip capabilities rather than solely relying on costly DFT approaches. We outline a tolerance analysis methodology for test signal propagation to be utilized in hierarchical test generation for analog circuits. A detailed justification of this proposed novel tolerance anal...

The traditional approach to validate analog circuits is to utilize extensive SPICE-level simulations. The main challenge of this approach is knowing when all important corner cases have been simulated. A new alternative is to utilize formal verification techniques. This paper utilizes a simple example to illustrate the potential flaws of a simulation-only based validation methodology and the po...

Carbon Nanotube Field Effect Transistor (CNFET) is a promising new technology that overcomes several limitations of traditional silicon integrated circuit technology. In recent years, the potential of CNFET for analog circuit applications has been explored. This paper proposes a novel four quadrant analog multiplier design using CNFETs. The simulation based on 32nm CNFET technology shows that t...

Nowadays, due to the increasing complexity of circuits and systems incorporating mixedsignal components, many designers recognise the advantages of, and in some cases the necessity for, mixed-signal modelling and simulation of the circuits and systems as a whole prior to, during and post production of the circuit or system. This is particularly so within the microelectronics (semiconductor) are...

Artificial neural networks are applied for modelling the input circuits of the digital part at the analogue/digital interface in mixed-mode circuits. The generalization property of the neural networks is exploited to apply the models in a set of previously unknown situations. It is also shown that mixed-level analogue behavioural simulation is enabled if the same modelling concept is applied.

We briefly review what a quantum computer is, what it promises to do for us and why it is so hard to build one. Among the first applications anticipated to bear fruit is the quantum simulation of quantum systems. While most quantum computation is an extension of classical digital computation, quantum simulation differs fundamentally in how the data are encoded in the quantum computer. To perfor...

Quantum effects of fields on curved spacetimes may be studied in the laboratory thanks to quantum fluids. Here we use a polariton fluid study Hawking effect, correlated emission from vacuum at acoustic horizon. We show how out-of-equilibrium physics affects dispersion relation, and hence propagation waves: properties either side horizon are critical observing effect. find that optimised by supp...
