Abstract
Green Design is to save the resource and energy for earth. Applying the recycling of energy concept to the electrical and electronic device and circuit, we can save many nuclear power plants to save the earth and human society. Comparing with today power amplifier PA has only 10% efficiency, the high linearity and high efficiency power-managing amplifier PMA and differential power managing amplifier DPMA can have the power efficiency more than 95%. The recycling switch inductor drive power management unit PMUx gets rid of the switch loss and has power efficiency more than 99%. The Xtaless Clock generator based on on-chip gain-boost-Q LC tank and the Spurfree and Jitterless Frequency & Phase Lock Loop FPLL. The DPMA directly supply the power to the plasma light. The charge doped light mirror reduces the voltage swing, increases the power efficiency and operating speed of plasma light, projective TV, LaserCom. The plasma light can use for the home light to have the efficiency of 95% to replace the conventional light bulb having only 10% efficiency. The bipolar LED serves as both thermal detector and fault indication light saving a lot of energy and enhances the safety of electrical vehicle. The resistorless-zero-current-detector saves a lot of power dissipation in the PMU. The 5-less green SOC design of Xtaless clock generator, the capless LDVR (low drop voltage regulator), the inductorless SM (Switch Mode Power Regulator), resistorless current detector and diodeless TRNG (True Random Number Generator) can save the earth.
