Design techniques for IIR filters operating on oversampled delta-sigma (Delta Sigma)
modulated signals are presented. It is shown that Delta Sigma-based IIR filters can be …

This is a thesis about implementation of a∆ Σ modulator with continuous-time techniques. A
methodology to obtain proper continuous-time (s-domain) transfer functions for a continuous …

In this paper efficient digital filter design techniques categorized as sigma‐delta modulation
based short word length (SWL) and multibit (or contemporary) techniques are reviewed in …

A design methodology for realising IIR filters on sigma-delta modulated signals is proposed.
It is shown that only 3N adders together with minor logic are required to implement an Nth …

This paper presents an approach for implementing continuous-time adaptive recursive
filters. The resulting filters should be capable of operating on much higher signal …

An adaptive filter technique for tuning continuoustime integrated filters is presented. This
adaptive technique is based on the model-matching configuration and tunes both the poles …

An adaptive analog notch filter is proposed for applications requiring high frequency
adaptive signal processing. Based on a log filter circuit topology, this filter design suggests …

How adaptive algorithms can be applied to low-sensitivity digital filter structures is shown.
The considered structure is derived by a bilinear transformation of an analog doubly …

In many applications, it is desirable to synthesize an adaptive impedance to match some"
real world" system, so that when the target impedance changes, the matching impedance …

A design methodology for realizing IIR (infinite impulse response) filters on sigma-delta
modulated signals is proposed. It is shown that only 3N adders together with minor logic are …
