Current-mode high-frequency wavelet filter based on leap-frog multiple-loop feedback structure

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

A method is proposed to realize high-frequency wavelet transform in analogue filter by employing Gm-C circuits and current-mode leap-frog multiple loop feedback structure in this paper. Also, to enhance the performance, the fully differential Nauta transconductor is utilized as the Gm cell in the design. The Marr wavelet is used as an example, with the design procedure illustrated. Using standard TSMC 0.18μm CMOS process, simulation results show that the center frequency of the Marr wavelet filter ranges from 63MHz to 142MHz by tuning supply voltage. The total power consumption is 69mW at 100MHz.
