Non-Ideal Amplifier effects on the accuracy of analog-to-digital capacitor ratio converter
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2001Co-Authors: Wooyoung Choi, R. Harjani, B. VinnakotaAbstract:The performance of switched capacitor based successive approximation data converters is limited by the matching of capacitor ratios. In previous work we have shown that switched capacitor ratios can be precisely measured using an AD-CRC. In this paper, we analyze and simulate the impact of the non-Ideal Amplifier behavior on the accuracy of the measured capacitor ratio. We derive closed form equations which describe time-domain relation between the specifications of the Amplifier and the accuracy requirements. These relations are used to derive an optimal set of specifications for the Amplifier in the AD-CRC.

analysis of optical back propagation under non Ideal optical phase conjugation and Amplifier noise
Photonics North, 2014Co-Authors: Guanhui Wang, Mohammad Rezagholipour Dizaji, Lawrence R ChenAbstract:Investigation of optical back propagation performances under some practical impairments such as non-Ideal optical phase conjugation and non-Ideal Amplifier noise is presented. The results can also be used to determine the optimum operating system parameters under non-Ideal conditions.

Concept of the Ideal Amplifier and its application for creating cascade Amplifier systems
Solid State Lasers VIII, 1999Co-Authors: Vladimir A. Mishin, Sergei A. Vasiliev, M A Kuz'minaAbstract:Because of the development of laser technologies, in particularly of the method of laser isotope separation, the necessity to develop kilowatt-class narrow-band tunable laser systems has increased. Organic dyes solutions are the unique active medium that allows to realize laser systems with such characteristics. However the dye solution is a rather complex medium and a careful optimization of the laser system parameters is required to reach a high efficiency. A large number of publications concerning the powerful dye laser systems is devoted to the research of a single Amplifier stage. In the present paper the cascade of the dye laser Amplifiers is considered as a unit. On the basis of a simplified model of the Amplifier stage, the equations describing the whole laser system were solved analytically. Such approach has allowed, on the basic parameters of the laser system, (input and output power, characteristic of active medium) to determine optical parameters of each Amplifier stage in the cascade (number and parameters of stages, pump power distribution between stages). On the basis of the offered model the optimization of the 1 kW dye laser system, pumped by copper vapor laser, was carried out. Analytical estimations were compared with the results of a rigorous numerical simulation of the system.
