Abstract :
This Letter presents two simplified expressions to determine the fractional shifts in ω0, and Q of the active filters due to the finite gain-bandwidth of the op amps. The expressions are functions of the coefficients of the characteristic equation of the filter. An example is included to illustrate the simplicity and usefulness of the derived expressions
