A general method for analogue implementation of high-frequency wavelet transform is proposed in which the wavelet transform is synthesized by a bank of Gm-C bandpass filters whose impulse responses are the mother wavelet and its dilations. The proposed approach employs the inverse follow-the-leader-feedback multiple loop feedback structure for filter design to lower the magnitude sensitivity and facilitate...
A high-frequency wavelet filter which employs Gm-C blocks based on leap-frog (LF) multiple-loop feedback (MLF) structure is presented. The proposed method is well suitable for high-quality high-frequency operation since the Gm-C based filter can achieve high frequency, whilst LF MLF configuration has the characteristics of lower magnitude sensitivity and capability of realizing arbitrary rational...
Two CMOS fifth-order gm-C elliptic lowpass filters based on the current-mode multiple loop feedback (MLF) leap-frog (LF) and follow-the-leader-feedback (FLF) configurations are designed. The filters are implemented using a fully-differential linear operational transconductance amplifier (OTA). PSpice simulations using a standard TSMC 0.18mum CMOS process with 1.8V power supply have shown that the...
The design and implementation of a CMOS current- mode fourth-order Butterworth continuous-time leap-frog (LF) multiple loop feedback (MLF) lowpass filter is described. The filter is implemented using a fully-differential linear, low voltage and low power operational transconductance amplifier (OTA). PSpice simulations using a standard TSMC 0.18 mum CMOS process with 1.5 V power supply have shown that...
The design and implementation of a CMOS continuous-time follow-the-leader-feedback (FLF) filter is described. The filter is implemented using a fully-differential linear, low voltage and low power consumption operational transconductance amplifier (OTA) based on a source degeneration topology. PSpice simulations using a standard TSMC 0.18 mum CMOS process with 2 V power supply have shown that the...
Read/write channels for hard disk drives (HDD) require high-frequency continuous time filters (CTF). A 650 MHz current-mode seventh-order 0.05deg equiripple linear phase low-pass filter for computer hard disk read/write channels with data rates up to 1 Gbit/s is presented in this paper. It is implemented in CMOS using a leap-frog multiple loop feedback structure. The operational transconductance amplifier...
A 400 MHz CMOS fifth-order linear phase gm-c filter based on current-mode (CM) leapfrog (LF) structure is realized. The filter is implemented using a fully-differential linear operational transconductance amplifier (OTA) based on source degeneration topology. PSpice simulations in a standard TSMC 0.18 mum CMOS process and with 2.5 V power supply have shown that the cut-off frequency of the filter...
