        Abstract
        A minimum component high frequency Gm-C wavelet filter structure is presented. A simple function from Maclaurin series approximation is used and the current-mode follow-the-leader feedback structure is employed. For the seventh-order Marr wavelet bandpass filter, the proposed implementation architecture contains only seven ideal Gm-C integrators for poles and one transconductor for zeros. A 100 MHz wavelet filter has been designed and simulated in 0.18 m CMOS and results show the feasibility of the proposed approach.
