Abstract
Features and advantages of the present disclosure include a multimode voltage controlled oscillator (VCO). In one embodiment, a circuit comprises a VCO, first and second transistors, and first and second capacitive attenuators. The first and second transistors are cross coupled through the attenuators. In a first mode, the first and second transistors are turned off, and the capacitive attenuators attenuate a signal on output terminals of the VCO at control inputs of the first and second transistors. In another mode, the first and second transistors are turned on, and the capacitive attenuation is reduced or turned off so that control inputs of the first and second transistors receive signals on the outputs of the VCO.
