This study presents an ultra-low-power, low-phase noise, and small-size voltage-controlled ring oscillator for use in implantable electronics operating in the Medical Implant Communication Service (MICS) frequency band and 65-nm IBM CMOS technology. This five-stage voltage-controlled ring oscillator does not require external inductor and capacitor similar to other LC oscillators, and hence, requires very small die area. A new methodology to design them has been employed in this study, and for… CONTINUE READING
