The present invention provides a semiconducting structure including a substrate having an SOI region and a bulk-Si region, wherein the SOI region and the bulk-Si region have a same or differing crystallographic orientation; an isolation region separating the SOI region from the bulk-Si region; and at least one first device located in the SOI region and at least one second device located in the bulk-Si region. The SOI region has an silicon layer atop an insulating layer. The bulk-Si region further comprises a well region underlying the second device and a contact to the well region, wherein the contact stabilizes floating body effects. The well contact is also used to control the threshold voltages of the FETs in the bulk-Si region to optimized the power and performance of circuits built from the combination of the SOI and bulk-Si region FETs.

The present device generally relates to a waterless electronic hookah machine. The waterless electronic hookah machine has a main body portion, a handle section and a flexible wire cable (or “connector”). The flexible wire cable electrically connects the main body portion with the handle section. The handle section has a removable mouthpiece containing a cartridge having a liquid. When a user activates a push button or vacuum switch on the handle section, a power source in the main body portion sends power through the flexible wire cable to an atomizer located in the handle section which then heats the liquid in the cartridge of the mouthpiece and a vapor is created for the user to inhale. The device allows multiple users (generally up to six) to use the device at the same time wherein each user may experience a different flavor smoke. Flavors may be easily switched without the need to rinse out the electronic hookah machine. The user is able to adjust the voltage going to the handle.

The invention is directed to a system and method for regulating a load (such as a CPU). A pulse-width-modulation (PWM) regulator calculates the duty cycle of the control pulse from a PWM controller, and then compares the duty cycle to a predetermined threshold. Thereafter, the PWM regulator regulates working conditions, such as clock frequency, supplied voltage, or fan spin speed, based on the above comparison.

An RFID tag capable of enhancing the reliability of products and an RFID system having the same are provided. The RFID tag includes a tag antenna receiving waves from an RFID reader, and a tag driver. The tag driver includes an accumulation mode capacitor adjusting a capacitance value corresponding to an input voltage. That is, the tag driver adjusts the amplitude of a modulated carrier wave using the accumulation mode capacitor. Accordingly, the RFID tag adjusts the impedance of the tag driver without adjusting the current transmitted from the tag driver. Therefore, impedance adjustment of the tag driver can prevent the voltage transmitted from the tag driver from being lower than the reference voltage, and modulation and demodulation can be stably performed. As a result, the reliability of products can be enhanced.
