Abstract:
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 4th generation 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.
