Low-Power Relaxation Oscillator With Temperature-Compensated Thyristor Decision Elements


This paper presents a low-power 140 kHz relaxation oscillator (ROSC) for low-frequency clock generators and timers. In voltage-mode ROSCs, unavoidable shunt current consumption results from voltage slewing at the integration capacitor. The proposed circuit employs CMOS thyristor-based decision elements which effectively reduce shunt currents by exploiting internal positive feedback. A complemen... » read more

System Bits: Feb. 23


Making electrons act like liquid While electrical resistance is a simple concept in that rather like friction slowing down an object rolling on a surface, resistance slows the flow of electrons through a conductive material, and now, MIT professor of physics Leonid Levitov and Gregory Falkovich, a professor at Israel’s Weizmann Institute of Science have found that electrons can sometimes tur... » read more
