摘要： The present disclosure provides methods and apparatus for dynamically adjusting the common mode voltage at the LC tank node and/or the power supply voltage of a VCO with an LC resonator in order to force oscillation start-up by temporarily increasing gain. Methods according to certain preferred embodiments may reduce power consumption and/or overcome threshold voltage limitations and/or increase frequency and frequency tuning range during normal (steady-state) operation.
