Signal frequency bandwidth limitation, fast pulse shaping,
separation between telecommunications signals, and suppression
of unwanted carrier and disturbance frequencies are
among the most important jobs of filter circuits. While
active filters with operational amplifiers and switched capacitor
filters are used for lower frequency applications,
passive filter versions dominate the application spectrum at
frequencies above 5MHz. Now, however, a new active filter
design has been developed that makes use of the open loop
pole and delay time of an operational amplifier. The filter
circuits consist of OPA660s, which provide the necessary
bandwidth and allow access to the first open-loop pole and
internal amplifier delay time.
