摘要: This article proposes a new type circuit of Rotary Traveling Wave Oscillator, which using cascaded Pull-up and Push-down cells to compensate energy losses. The structure can not only avoid short-circuit power in conventional inverter-based oscillator, but also effectively control the rotation direction rotary oscillator. Both EM analysis are carried out TSMC 65nm standard CMOS technology. HSPICE results show that, proposed oscillator save total 6.65% than with normal thick top metal, about 25.97% saving be achieved by ultra-thick metal.
