200GHz CMOS Prescalers with Extended Dividing
... closer. As a result, when voltage injection occurs at an instance outside of the output crossing time period of the prescaler, the voltage injection tends to pull outputs toward it. In case the prescaler’s natural oscillation frequency is close to half of the injection frequency, such an effect will ...
