The low-pass filter shown in
require external capacitors and uses only three
external resistors; the op amp’s GBWP sets the corner
frequency. R
is used to set the Q. To avoid gain peaking in the
frequency response, Q needs to be low (lower values
need to be selected for R
bandwidth varies greatly over temperature and
process. This configuration, however, provides a low
cost solution for applications with high bandwidth
requirements.
