Modular multiplication is the fundamental operation in most public-key cryptosystem. Therefore, the efficiency of modular multiplication directly affects the efficiency of whole crypto-system. This paper presents implementation and comparison of several recently proposed, highly efficient architectures for modular multiplication on FPGAs: interleaved multiplication, two variants of Montgomery multiplication, Jeong-Burleson multiplication, multiplication based on key size partitioning and complement. Finally, new hardware architecture for time optimal modular multiplication is proposed based on Hamming weight and position of one's in multiplicand.

A 16-bits Constant-Current LED Driver Integrated Circuit (abbreviated as “Driver”) is presented in this paper. It is fabricated with 0.6-µm 2P3M CMOS process in an active area of 0.9mm × 0.9mm. The driver provides 16 open-drain, constant current sinking LED driver outputs. All the constant-current outputs are programmed together by a signal external resistor. Post simulation result shows that each output channel provides constant current up to 70mA within possible temperature range of −40°C to 125°C and power supply range of 3V to 5.5V. The current match between each bit is 3% and between each technical corner is less than 6% typically. More importantly, it includes the power-on reset and over-heating protection circuits, which help protect the IC against logic error and burnt up.

The formulas were derived for the calculation of the permittivity of dielectric measured in TE109 mode rectangular cavity and TE011 mode cylindrical cavity. A testing system based on scalar network analyzer was adopted to measure the same sheet dielectric by the two cavities above respectively. The testing software based on LABVIEW was developed. The results showed that the measuring error was less than 3.8% and repeatability error was than 1.1% by perturbation method in rectangular cavity, while those are 0.4% and 0.3%, by using cylindrical cavity. The automatic measurement of permittivity of dielectric sheet can be achieved by perturbation method in cylindrical cavity.

This paper introduces a design of slope compensation circuit for peak-current-mode boost DC-DC converter. The circuit is simple, and eliminates instability problem of the peak-current-mode system generated by double-loop control. And it avoided detrimental effects on account of improper compensation, such as slow transient response, low carrying capacity. It improves the stability of the switching power supply. The design is implemented base on the TSMC's 0.35 μm CMOS process. The spectre simulation results show that, when the inductive current occurs disturbance, the system do not occur prolonged oscillation, can supply stable output voltage.

In this paper, the game between government and real estate developers is modeled based on nonlinear dynamical equations. In the model, chaotic behavior is observed, and the time-delayed feedback control (DFC) method is introduced to control chaos to converge to the equilibrium point within minimum number of iterations. Furthermore, a method of optimizing the regulating parameters is presented. In this method, computational verb rules (CVR) are used to approximate the optimal control parameters. The simulation results show that by using CV rules, the convergent time is reduces dramatically comparing with the conventional price perturbation control method.

A second-order compensated bandgap reference (BGR) using current proportional to absolute temperature (PTAT) is proposed in this paper. This proposed BGR utilize a PTAT current to improve the temperature coefficient (TC) of base-emitter voltage VBE, and make temperature characteristic of the BGR optimized. The simulation based on nee 2um BiCMOS process library shows a lower TC (only 9.07 ppm/°C) and a variation in the output voltage of the BGR less than 3.7mV with a power supply range from 3V to 10V.
