Varactor-free amplitude controlled oscillator(ACO) for system on chip and system on card Xtaless clock SOC

th The fundamental breakthrough in green technology are the Varactor Free Amplitude Controlled Oscillator VFACO and the planar EMI-Free Planar Inductor. The VFACO makes the fine tune for oscillation frequency. It has the frequency compensation over temperature. It doesn't have the VCO self-modulation-induced phase noise. It is phase-noiseless. It is high-Q and high stability. It increases the communication capacity. The EMI-Free Planar Inductor is the backbone of the platform of green technology. The platform of green technology contains the Xtaless ClockChip, Inductorless PMU & PA and ESDS-PCB to provide the green technology for green chip design. Especially for the 4generation wireless communication, the Inductorless PMU & PA are the most important green technology. The Xtaless ClockChip adopts the most advanced self-compensation Amplitude controller. The ESDS-PCB has the minimum Via assignment algorithm to make the optimum pin assignment for the platform of green technology. The self-compensation Amplitude controller is so powerful that the Xtaless ClockChip is trimless and/or trimfree Xtaless ClockChip. It is plastic-packageable and IP-able Xtaless ClockChip that it is the only market-ready-product Xtaless ClockChip.
