Analysis and design of bandpass delta-sigma A/D converters

Creator:: Zhai, Dalun
Abstract:: A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation is employed to realize a RAM-type pseudo-2-path lossless integrator. The bandpass second-order and 4th-order delta-sigma...

MOS switched-current biquadratic filters

Creator:: Lee, Bor
Abstract:: A MOS biquadratic (biquad) filter employing the switched-current technique is reported. The circuit uses current-mode processing which can offer wide bandwidth, low voltage operation, and can be implemented with standard CMOS technology. Examples of lowpass, highpass, and bandpass filters are given which illustrate the synthesis procedures and the versatility of...

Optimizing the microcode produced by a high level microprogramming language

Creator:: Ma, Perng-Yi
Abstract:: The purpose of this research is to develop methods to translate a certain machine independent intermediate language (IML) to efficient horizontal microprograms for a class of microprogrammable machines. This IML has been developed by Malik (12) and is compiled directly from a high level microprogramming language used to implement a...

Analysis and measurement of charge injection in switched-capacitor circuits

Creator:: Shen, Min
Abstract:: It has been verified by theoretical analysis, circuit simulation and test that two switch transistors in parallel in a simple sample and hold circuit can be achieve high speed with low error voltage due to charge injection. The wide transistor provides low RC time constant when it is closed and...

Design, fabrication and characterization of complementary heterojunction field effect transistors

Creator:: McMahon, Terry E. (Terry Edwin), 1963-
Abstract:: Complementary delta-doped AlGaAs/GaAs Heterojunction Field Effect Transistor (CHFET) devices and circuits were fabricated using MBE and a 2μ non-planar gate recess process. Several schemes were used in an attempt to improve the performance of the p-channel HFETs. These included delta-doping, carbon-doping and dipole-doping. Circuits and individual n- and p- channel...

Active power filter for the cancellation of harmonic line current distortion

Creator:: Merk, Marcel
Abstract:: With the increased attention on high efficiency and energy savings, power electronic energy conversion equipment is increasingly incorporated in all levels of the power system. The drawback of such equipment is the generation of nonsinusoidal currents in the power distribution network due to the nonlinear operation. Harmonic currents may distort...

Design procedure for brushless doubly-fed machine used as a limited speed-range pump drive

Creator:: Alajmi, Abdulhadi M.
Abstract:: The continuing desire of industry to further improve process efficiency, through tighter control and energy conservation, has prompted users to pay closer attention to Adjustable Speed Drives (ASDs). The conventional ASDs consist of induction or synchronous motors controlled by power electronic controllers through the adjustment of supply frequency and line...
