The purpose of this paper is to present a new design configuration for multicoupled band-pass filter based on Mason's loop rule, together with the negative feedback topology and to compare it with Leap Frog (LF) and Follow the Leader Feedback (FLF) design examples.

This thesis presents the analysis and characterization of a low sensitivity dual feedback active RC bandpass filter. Chapter 2 details the analysis of the network and a method of simplifying the resultant transfer function by a single pole/zero cancellation. Chapter 3 characterizes the simplified transfer function through an analysis of the quality factor and of the center frequency gain as functions of the individual variables of the circuit. It also details sensitivity analyses of these characteristic quantities and a stability analysis. Lastly, chapter 3 presents graphical representations of the equations developed so that they can be used as design tools. It then goes through the details of applying these graphs to an example network. Chapter 4 explains the differences between experimental data and predicted data by discussing some of the nonlinearities neglected in the original analysis. Finally chapter 5 restates the design technique in light of the predominant nonlinearities.

This study proposes employing new filters in various configurations for use in digital communication systems. We believe that significant improvements in such performance areas as transmission rate and synchronization may be achieved by incorporating these filters into digital communications receivers. Recently reported in the literature, these filters may offer advantages over the matched filter which allow enhancements in data rates, ISI tolerance, and synchronization. To make full use of the benefits of these filters, we introduce the concept of parallel signal transmission over a single channel. We also examine the effects of signal set selection and noise on performance.

A variable gain, high linearity, low power baseband filter for WLAN applications is implemented in a 1.5 V 3 V 0.15 ��m CMOS process. This fourth-order low-pass filter, which is introduced in the transmit channel as a reconstruction filter between the D/A converter and the mixer, has a measured cut-off frequency of 9 MHz. The active-RC configuration has single amplifier biquads (SABs) to save power and is implemented using three-stage opamps with nested-Miller compensation for better linearity. It also features a special ��-to-Tee transformation network for the resistor arrays, used for frequency or gain trimming, in order to obtain higher linearity than conventional Sallen-Key circuits. The measured THD for a 2 V [subscript p-p] signal at 1 MHz is -72 dB. / Graduation date: 2004
