Title Proper : AUTOMATIC TUNING OF HIGH-Q FILTERS BASED ON ENVELOPE DETECTION
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : An abstract of the dissertation of Aydm iucer Karqllayan for the Doctor of Philos-ophy in Electrical and Computer Engineering presented January 6, 2000.Title: Automatic Tuning of High-Q Filters Based on Envelope DetectionAn automatic mixed-mode tuning scheme suitable for analog filters with largequality factors and very high operating frequencies is presented. The highest fre-quency of operation is determined by two envelope detectors which do not needto be accurate as long as they are matched. Beyond the envelope detectors, thetuning operation uses only DC values and low-frequency logic signals. The tun-ing scheme assumes that the filter's quality factor, Q, is large enough so that thetransfer function magnitude has a peak. Systematic tuning errors become smallerwith increasing Q. The tuning circuitry is small and simple so that the area andpower overhead required for tuning is minimized. The operation of the tuningcircuit is insensitive to amplifier delays and offsets. The method can be used forhigh-Q bandpass, lowpass and highpass sections and can be applied to master-slaveand off-line tuning configurations.The circuit is implemented in a standard CMOSprocess; it operates on a single 3-.......-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
