Abstract :
This paper proposes a design method for integrated continuous-time filters with low group-delay sensitivities. For minimization of worst-case errors of a group delay by deviations of element values, the sum of absolute values of group-delay sensitivities for element values is considered and conditions for the minimization are proved. Although equations of group-delay sensitivities only at DC are used for the determination of element values in general signal-flow graphs, relatively low sensitivities at the other frequencies are confirmed by computer analysis
