| dc.description | In some applications, filtering circuits whose response have a short transient time
are necessary. In the classical approach of filter design, the designer has no much
options to manipulate the filter characteristics in the time domain because the design
formulae affects the frequency-domain specifications. Parameter-varying filters
posses as a chief characteristic their short transient time duration, which makes them
suitable for applications in which speed is a mandatory need. The short transient is
the result of a temporary variation of one or more of their descriptive parameters.
Despite this advantageous feature, that has been demonstrated with solid theoretical
analyses, there is still a bottle-neck in the practical implementation of these kinds of
filters.
In this work, an implementation of a parameter-varying filter based on switchedcapacitors
(SC) is presented. This implementation is a second-order low pass SC
filter on a FPAA (Field-Programmable Analog Array) development board. Theoretical
aspects related to this implementation are reported, in particular stability
and homogeneous response analysis. Experimental results of the parameter-varying
implemented filter are presented and compared with the time-invariant counterpart.
In summary, the theoretical analysis and the experimental results support the
feasibility of implementing parameter-varying filters with switched-capacitor techniques. | |
