Publication number: 20100301957Abstract: Disclosed herein is a relaxation oscillator using a spintronic device. The relaxation oscillator includes a power source unit, a spintronic device, and a capacitor. The power source unit applies power. The spintronic device is driven by the power applied by the power source unit, and has a variable voltage value depending on the intensity of a magnetic field. The capacitor is connected in parallel with the spintronic device, and is discharged when it assumes a minimum-voltage value in the threshold voltage range of the spintronic device and charged when it assumes a maximum voltage value in the threshold voltage range.Type: ApplicationFiled: July 20, 2009Publication date: December 2, 2010Applicant: Korea Basic Science InstituteInventors: Seung Young Park, Younghun Jo
