Description
Summary:This paper demonstrates a CMOS Ring Voltage Controlled Oscillator (RVCO) whose oscillation frequency is insensitive to supply noise. Our RVCO achieves this with on- chip adaptive bias-current and voltage-swing control. A prototype RVCO is fabricated with 0.13um CMOS technology and it achieves static supply voltage sensitivity of 0.013%-f vco /1%-V dd and dynamic sensitivity of 0.08%-f vco /1%-V dd .
