A multi-bit Delta-Sigma ADC employing a nonlinearity suppressed feedback DAC is presented in this paper. Methodologies for a mismatch-insensitive design are proposed and investigated. Measurement results from prototypes fabricated in a 0.13μm process demonstrate that without dynamic-element-matching or calibration techniques, the Delta-Sigma modulator employing a 7-level feedback DAC achieves a SFDR...
Dolby Laboratories provides a detailed flow of operation of the Composite multichannel audio compression algorithm, from receiving a frame in the input data buffer all the way to outputting PCM audio signals, in the form of a C-like floating-point pseudocode. This pseudocode helps the licensees in understanding the details in implementing a real-time AC-3 decoder. A set of bitstreams or test vectors...
This paper studies optimal control in a sensor network system consisting of mobile robots to minimize the overall energy consumption of the whole network. With communication energy cost and mobility energy cost taken into consideration, the problem is formulated as an optimal control of a hybrid system, which is solved by switched Linear Quadratic Regulator (LQR). Though switched LQR obtains globally...
This paper describes a thyristorized static switch designed for the operation of Direct On Line starter fed three phase induction motor drive. It establishes the fact that optimum value of firing angle combination for the voltage controller of induction motor depends on the motor parameters. Motors having different parameter values with identical rating are considered for the work. Optimum firing...
This paper establishes the fact that optimum value of firing angle for the thyristorized voltage controller fed induction motor at starting depends on motor parameters. Identically rated motors with different parameter values are considered for the work. Extensive simulations are carried out to obtain the optimum firing angle of the voltage controller, which gives zero negative torque pulsations with...
