Electronically tunable current-mode biquadratic circuit using current controlled unity gain cells
Ayumu Karita,Takao Tsukutani,Noboru Yabuki,Yasuaki Sumi 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7
This paper introduces an electronically tunable current-mode biquadratic circuit employing current controlled unity gain cells. The circuit is constructed with two current controlled current followers (CCCFs), two CCCFs with voltage buffers (CCCFBs) and two grounded capacitors. The circuit can realize low-pass, band-pass, high-pass, band-stop and all-pass transfer functions by choosing appropriate current input and output terminals without any component matching conditions. Additionally, the circuit parameters ω? and Q can be tuned orthogonally through adjusting the bias currents. The biquadratic circuit enjoys very low sensitivities with respect to the circuit components. An example is given together with simulated results by PSPICE.
A Study on Road Sign Shape Recognition Using Active Net
Fukuya NAMBA,Yasuaki SUMI,Noboru YABUKI,Takao Tsukutani 대한전자공학회 2007 ITC-CSCC :International Technical Conference on Ci Vol.2007 No.7
On Intelligent Transport Systems, the road sign detection and recognition from landscape images is actively developed. The examination case was only seen on the shape recognition as the preprocessing of extraction by Active Net. So this paper shows the post processing of extraction and we have succeeded a process application on road sign shape recognition by Active Net.
Electronically tunable multiple-mode biquadratic circuit employing OTAs and grounded capacitors
Hiroki Kawakami,Takao Tsukutani,Noboru Yabuki,Yasuaki Sumi 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7
This paper introduces an electronically tunable multiple-mode biquadratic circuit employing operational transconductance amplifiers (OTAs) and grounded capacitors. The basic circuit configuration is obtained from a second-order integrator loop structure consisting of loss-less and lossy integrators. The multiple-mode biquadratic circuit can realize low-pass, band-pass, high-pass, band-stop and all-pass transfer functions by suitable choosing the current output terminals. Additionally, the circuit parameters ω?, Q and H can be set orthogonally through adjusting the bias currents of the OTAs. The biquadratic circuits enjoy very low sensitivities with respect to the circuit components. Some examples are given together with simulated results by PSPICE.

In this paper, we have described the new All-Image DCDAM that introduces BL-DCDAM into conventional All-Image DCDAM that we have proposed before. BL-DCDAM adopts the algorithm independent on the order of presenting the input vectors. To our research, BL-DCDAM is effective because we used all pixels of the input image as the input vectors. New All-Image BLDCDAM has obtained a correct result even in the case that conventional one has failed from the experiment.
