Item type:Item, Analysis parameter PID with the root locus theory by used M-file mat lab(2012-01-01) ;Kraisuntronlertphop, A.Gunpanich, S.This paper presents the program M-file with Mat lab for PID parameter by root locus technique. The program can be used with other transfer function of any plant. The characteristics of the M-file can be defined for transfer function, percent overshoot and settling time to study the responding of this theory, the simulink Mat lab will be used to simulate the parameter set by M-file. - Some of the metrics are blocked by yourconsent settings
Item type:Item, Current mode automatic gain control(2008-01-01) ;Kasemsuwan, VarakornArthansiri, TeerawatThis paper presents a current mode automatic gain control (AGC) using a new current mode pseudo exponential-control variable gain amplifier (VGA). The VGA is based on the 4<sup>th</sup> order Taylor's series approximation to obtain a large control range. The circuit Is designed using CMOS technology and can operate with ± 1 V supply voltages. The control range is 25 dB with the maximum error less than 0.5 dB. The power dissipation is 3 mW.
