Artículo:: A low-voltage band-gap reference circuit with second-order analyses
Autor:: Chao-Jui Liang
Resumen:: A power-saving band-gap reference (BGR) circuit for low-voltage operations is proposed by Chao-Jui Liang, Chiu-Chiao Chung and Hongchin Lin using the sub-threshold current source and a fraction of VBE in parasitic bipolar transistors to generate a reference voltage of 170?mV with chip area of 0.029?mm2

Artículo:: On the simulation of fast settling charge pump PLLs up to fourth order
Autor:: Marco Guermandi
Resumen:: We discuss three different models for the simulation of integer-N CP-PLLs, namely the continuous time and discrete time z-domain approximations and the exact semi-analytical time-domain model. The limitations of approximated models are analyzed in terms of settling time and output spectral purity estimation for fast settling PLLs up to fourth order. As a case study the three models are applied to a fast switching PLL targeting WiMedia MB-OFDM UWB systems

Artículo:: Simple implementation of control gate signals for the interleaved LLC resonant converter for high current application
Autor:: Myung-Bok Kim
Resumen:: A novel method of the gate signal generation for the interleaved LLC converter is proposed, which is based on the relationship between the output signal of a toggle flipflop having the double period of the input clock signal and the output gate signal of the LLC controller having almost half duty cycle. The gate signals for the master and slave converters are generated using the rising and falling edge instants from the original control gate signal of the controller, respectively. Therefore, the required 90 degree phase difference between two signals can be always kept at any instant and at any output load condition

Artículo:: High-order sensitivity invariants
Autor:: Jacek Izydorczyk
Resumen:: The aim of the research reported in this paper is to extend the notion of invariant sensitivity sum, widely known for electrical networks, from first-order sensitivities to high-order sensitivities. The results are high-order invariant sums of sensitivities formulated for nonlinear lumped circuit. Invariant sums actually found for nonlinear lumped networks are generalizations of sums given earlier for linear lumped networks

Artículo:: Design of a two-output forward converter with an output voltage objective function
Autor:: Yu-Kang Lo
Resumen:: A new method is proposed to distribute the steady-state output voltage errors in a two-output forward converter. The cross-regulation among the two output voltages aredescribed in terms of the circuit parameters. An objective function is formed for each of the two outputs to track its reference within the specified error. The weighting feedback gains of the two output voltages can be determined by the presented control scheme which optimizes the objective function. The proposed method is suitable for a two-output system without a dominant load
