This paper describes the latest iteration of the SPICE research. SPICE 3 explains the process maturity framework to address the level III of the SPICE model. Building upon the developments of level II, SPICE 3 advocates establishment of a process improvement infrastructure to facilitate good practice sharing in construction organisations. To achieve SPICE level III process maturity, organisatio...

In this article three well known singleelectron tunnelling (SET) circuits are discussed. Both measurement results and simulation results on the three SET circuits are shown. The simulation results were obtained using a SPICE model for a single SET junction. The experimental data from SET circuits is used for validation purposes of the SPICE model. The SPICE model performed good on all experimen...

This paper is aimed at identifying the potential role of SPICE, especially SPICE level 3, to achieving the proposed UK public sector efficiencies. SPICE level 3 presents the process maturity framework to address the level III of the SPICE model. Building upon the developments of level II, SPICE 3 advocates establishment of a process improvement infrastructure to facilitate good practice sharing...

resonators. Higher order means more complexity in design. A third-order high-Q 300 kHz micromechanical bandpass filter, with Q-adjustment and frequency tuning, is analyzed using a parameterized cell library, "NODAS," for schematic representation and behavioral HDL simulation. An equivalent SPICE model of the filter is derived, which enables simulation in SPICE and comparison to NODAS. Frequency...

Figure 1. Basic IGBT subcircuit Introduction You’ve finally tested a version of your design that seems to work well, but you would feel a lot better if you KNEW the circuit would work well with all the devices that the vendor will supply in production. You found a model in a library, but you are not sure what specifications from the data book apply to that model. The following paragraphs will t...

An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...

This paper proposes a SPICE model development methodology for quantum-dot cellular automata (QCA) cells and presents a SPICE model for QCA cells. The model is validated by simulating the basic logic gates such as inverter and majority voter. The proposed model makes it possible to design and simulate QCA combinational circuits and hybrid circuits of QCA and other NANO devices using SPICE. In th...

Currently the UK construction industry is in search of continuous process improvement mechanisms, in order to improve quality and reduce construction time and costs. Likewise the software industry has been in search of process improvement frameworks, in the past decade. The Capability Maturity Model (CMM), developed by the Carnegie Mellon University, is one of the most widely adopted process im...

With single-electron tunneling (SET) technology it is possible to build electronic circuits with extreme low power properties. These SET circuits must therefore operate in the single electronics (current) regime. To simulate SET circuits in this regime, a SPICE model has been written. In contrast to the prescriptions in the so-called Orthodox theory of single-electronics, the SPICE model explor...
