Some general procedures for synthesizing filters using only RC elements and grounded voltage and current unity-gain amplifiers (GVTJGA's and GCUGA's) are discussed. Filters are designed according to theories with respect to minimum sensitivity to parameter variations by Calahan and Horowitz,. State-variable technique is also used to yield the optimal result in terms of the number of capacitors used and the spread of clement values. Another method, a coefficient-matching technique, leads to low-sensitive results with only three active elements. Sensitivity is investigated in each case and is found to be low for high value of the quality factor in most cases, and independent of element values in some cases ; thus high Q poles of bandpass filters are realizable in practice. Filters so designed also possess the desirable property of having a common ground for both the input and output ports. |
