NOVEL CMOS AND BICMOS ANALOG CIRCUITS AND SYSTEMS
HESHAM F. A. HAMED;
Abstract
The switched-current (SI) technique is a quite immature current-mode sampled-data processing technique. Further research and development has still to be done to make it competitive with today existing commercial techniques.
One of the objectives of this research is to investigate novel structures that are
advantageous compared to existing structures in terms of performance and signal processing accuracy.
Proposed techniques to improve the switched-current (SI) memory cell performance are presented. The first technique is mainly aimed to eliminate the charge injection in S21 memory cell that due to biasing current. The second technique is aimed to reduce the error due to non-zero output-input conductance ratio in the S21 memory cell.
In this thesis the advantages of using BICMOS current memory cell are presented. As application ofBICMOS current memory cell, a design procedure of a third order low pass elliptic filter is presented.
The techniques of programming Q and center frequency w 0 independently based on second generation switched-current technique are presented. The most important advantage of these techniques is that they do not use programming switches in the signal path.
A new approach to develop Field Programmable Analog Arrays (FPAAs) which is based on switched-current technique is presented. The Configurable Analog Cell (CAC) is based on switched-current integrator. This (CAC) is easily configured to perform basic functions such as amplifications, attenuation, inversion, summation and integration. These elementary operations may then be combined to obtain more complex signal processing, such as filtering and data conversion. The proposed FPAA architecture has many
