Item type:Publication, A capacitor-grounded current-tunable current mode all-pass network(2004-12-01); ; Dejhan, KobchaiA first-order current-mode all-pass section (CM-APS) using two current-controlled conveyors (CCCII) and a grounded capacitor are presented. The current-mode first order section consists of one single-output CCCII, one dual-output CCCII and one grounded capacitor. The circuit operation in current mode; and it can be directly employed as a subsystem of monolithic circuit. PSpice simulation results are carried out in order to verify the theory. © 2004IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Current-mode active-only universal filter(2006-12-01); ; Dejhan, KobchaiA universal current-mode active-only filter using the biquadratic transfer function is proposed. The proposed circuit is realized by minimized active-only components count without external passive elements. The different kinds of filter function as low pass, highpass, bandpass and band-reject response can be obtained without changing circuit topology. The proposed circuit is realized by using MOS transistors, OTAs, and OPAMPs. The parameters ω<inf>P</inf> can be electronically tuned through adjusting the transconductance gains of the OTA and Q<inf>P</inf> can be tuned by changing of their components without effect to ω<inf>P</inf> . The simulation results are given by PSpice. ©2006 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Log-domain multiphase sinusoidal oscillator(2011-10-13); ; Dejhan, KobchaiThis paper describes the design of a log-domain multiphase sinusoidal oscillator (MSO). The circuit is a direct realization of a first-order differential equation for obtaining the non-inverting and inverting lossy integrators. Each integrator comprises only a grounded capacitor and six transistors. The proposed MSO can be instantaneously controlled over wide frequency range by controlling the bias currents. The high-frequency of oscillation and oscillation condition can also be independently tuned which are indicated proposed MSO suitability in communications and high-frequency applications. The power consumption is obtained around 5.78mW at 100μA of bias current based on 2V single power supply. The oscillation frequency is controlled over four decades of frequency. The total harmonic distortion of four-phases (11.33MHz) is obtained around 1.12%. © 2011 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Single low-supply current-mode CMOS analog multiplier circuit(2006-12-01); ; Dejhan, KobchaiA simple structure of low-voltage current-mode CMOS analog multiplier circuit is presented. This multiplier circuit is based-upon quarter square algebraic identity technique by using CMOS technology. The transistors are operated in saturation region for different sub-circuits. The electronic resistor circuits are used as the input stage. The differential amplifiers are used for biased the squaring circuits. The current-mode operation can be obtained with a single supply, low-voltage, high-linearity and wide-bandwidth. This paper consists of 16 NMOSs with a 1.5 volts single supply. The achieved circuit performances have been carried out by PSpice. The input range is obtained more than ±100μA with linearity error less than 1%. The frequency response can be operated larger than 150 MHz. © 2006 IEEE. - Some of the metrics are blocked by yourconsent settings
