Abstract :
A novel output power-controllable configuration based on high-Q varactors has been proposed. The circuit configuration illustrates a high potential to be fabricated in integrated form. In addition, the adaptive technique allows the employment of high-Q bond-wire inductors with a certain degree of inductance deviation, which ensures very little power loss in the inductors.
