This paper presents a second order voltage mode quadrature sinusoidal oscillator using a recently reported active building block, namely the differential voltage current controlled conveyor transconductance amplifier. The circuit proposed here employs single differential voltage current controlled conveyor transconductance amplifier, two grounded resistors and two grounded capacitors. The use o...

introduction: considering high prevalence of epileptic disease and considering that 40 percent of epileptic patients are resistant to drug therapy, it needs more researches to find new therapeutic ways. lfs is among the new methods for epilepsy treatments. one possible mechanism involved in the anticonvulsant effect of lfs is increased adenosine. therefore, in this study the role of adenosine p...
