A Multiproject Chip Approach to the Teaching of Analog MOS LSI and VLSI
Multiproject chip implementation has been used in teaching analog MOS circuit design. After having worked with computer simulation and layout aids in homework problems, students designed novel circuits including several high
performance op amps, an A/D converter, a switched capacitor filter, a 1 K dynamic RAM, and a variety of less conventional MOS circuits such as a VII converter, an AC/DC converter, an AM radio receiver, a digitally-controlled
analog signal processor, and on-chip circuitry for measuring transistor capacitances. These circuits were laid out as part of an NMOS multiproject chip. Several of the designs exhibit a considerable degree of innovation;
fabrication pending, computer simulation shows that some may be pushing the state of the art. Several designs are of interest to digital designers; in fact, the course has provided knowledge and technique needed for detailed
digital circuit design at the gate level
On factorisation at small x
We investigate factorisation at small x using a variety of analytical and
numerical techniques. Previous results on factorisation in collinear models are
generalised to the case of the full BFKL equation, and illustrated in the
example of a collinear model which includes higher twist terms. Unlike the
simplest collinear model, the BFKL equation leads to effective anomalous
dimensions containing higher-twist pieces which grow as a (non-perturbative)
power at small x. While these pieces dominate the effective splitting function
at very small x they do not lead to a break-down of factorisation insofar as
their effect on the predicted scaling violations remains strongly suppressed.Comment: 17 pages, LaTeX. Updated version corrects some small misprints and

International Finance in General Equilibrium
Our purpose in this paper is to unify international trade and finance in a single general equilibrium model. Our model is rich enough to include multiple commodities (including traded and nontraded goods), heterogeneous consumers in each country, multiple time periods, multiple credit markets, and multiple currencies. Yet our model is simple enough to be effectively computable. We explicitly calculate the financial and real effects of changes in tariffs, productivity, and preferences, as well as the effects of monetary and fiscal policy. We maintain agent optimization, rational expectations, and market clearing (i.e., perfect competition with flexible prices) throughout. But because of the important role money plays, and because of the heterogeneity of markets and agents, we find that fiscal and monetary policy both have real effects. The effects of policy on real income, long-term interest rates, and exchange rates are qualitatively identical to those suggested in Mundell-Fleming (without the small country hypothesis), although our equilibrating mechanisms are different. However, because the Mundell-Fleming model ignores expectations and relative price changes, our model predicts different effects on the flow of capital, the balance of trade, and real exchange rates in some circumstances.Currency, cash, fiscal policy, montary policy, money, trade
The payout phase of pension systems : a comparison of five countries
This paper provides a comparative summary of the payout phase of pension systems in five countries -- Australia, Chile, Denmark, Sweden, and Switzerland. All five countries have large pension systems with mandatory or quasi-mandatory retirement savings schemes. But they exhibit important differences in the structure and role of different pillars, regulation of payout options, level of annuitization, market structure, capital regulations, risk management, and use of risk sharing arrangements. The paper summarizes the experience of these countries and highlights the lessons they offer to other countries.Pensions&Retirement Systems,Debt Markets,Emerging Markets,Insurance&Risk Mitigation,Investment and Investment Climate
