A pipelined baseband digital predistortion architecture for RF amplifier linearization

Creator:: Xu, Xiangqing
Abstract:: This thesis describes the design of a baseband digital predistortion architecture for radio frequency (RF) amplifier linearization. Existing amplifier linearization techniques are first examined. The nonlinearity of an amplifier can be characterized as amplitude-to-amplitude distortion and amplitude-to-phase distortion. The distortion can be corrected by providing a predistorted driver signal (both...

A controlled negative-resistance for realization of certain network functions

Creator:: Wagner, James Daniel
Abstract:: A circuit which functions as a controlled negative-resistance is described and analyzed; the circuit contains two transistors, a breakdown diode, and five resistors connected in a stable feedback configuration. From the analysis a set of design equations is derived. An experimental circuit is described and a comparison between measured performance...

Analysis of a tunnel-diode delay-line reflex memory cell

Creator:: Johnson, Ronald Lee
Abstract:: The operation of a tunnel-diode delay-line memory cell is examined in some detail, and a digital computer program which approximately simulates the operation of this memory cell is developed. The data from the computer simulation is compared with the available experimental data and found to agree very closely for clock...

Active network synthesis using operational amplifiers

Creator:: Chiang, Ching Hwa
Abstract:: Three synthesis methods for the realization of the voltage transfer function by means of RC elements and three different active devices are presented. These three devices are a high-gain amplifier, a voltage controlled voltage source (VCVS) and a negative immittance converter (NIC). The VCVS and NIC as well as the...

A linear circuit analysis program for a small computer with no auxiliary memory

Creator:: Stubkjaer, William Lloyd
Abstract:: A set of circuit analysis programs designed for the IBM 1620 computer (having 40,000 digits of memory) is described and its operation is explained. The set consists of d-c, a-c, and transient analysis programs. The d-c and a-c analysis programs provide the branch current and node-to-reference potential for linear circuits....

Energy-efficient clock generation for communication and computing systems using injection locking

Creator:: Ma, Chao
Abstract:: The design of high-performance, high-speed clock generation and distribution becomes challenging in terms of phase noise, jitter and power consumption, due to the fast development of communication and computing systems. Injection locking is a promising clocking technique since it can significantly improve the energy efficiency, suppress the phase noise of...

Nonlinear control applied to power systems

Creator:: Vedam, Rajkumar
Abstract:: When large disturbances occur in interconnected power systems, there exists the danger that the power system states may leave an associated region of stability, if timely corrective action is not taken. Open-loop remedial control actions such as field-forcing, line-tripping, switching of series-capacitors, energizing braking resistors, etc., are helpful in reducing...
