Granted: 2003-06-11
Abstract: A method of fabricating a trench flash memory device, where the method includes forming a patterned mask layer on the substrate and using it as the mask for form a trench in the substrate. Next, a source region is formed in the substrate around near the bottom of the trench, and followed by forming a tunnel oxide layer, a floating gate, a gate dielectric layer and a control in the trench. After removing the mask layer to expose the substrate, a drain region is further formed in the substrate. In this invention, since the trench flash memory device has a cylindrical shape with the tunnel oxide layer, the floating gate and the gate dielectric layer wrapping around the control gate, therefore the overlap area between the floating gate and the control gate is increased, resulting in a higher gate coupling rate (GCR), a lower required operation voltage and a higher device operation speed and efficiency.

IPC: H04L27/26
Filed: 2003-03-21
Granted: 2006-04-01
Abstract: The invention provides sampling clock compensation device of multi-carrier system and method thereof, which utilize the phase difference of the frequency response estimation values in two consecutive symbols of the system's subchannel to estimate the sampling frequency shift between the receiving end and the transmitting end of system. Further compensate the accumulated clock shift and phase rotation of the received signal at the receiving end due to the sampling frequency shift. When the accumulated clock shift is not large, the compensation device employs a phase rotation device to compensate the corresponding accumulated phase rotation in frequency domain. When the accumulated clock shift is too large, the compensation device corrects a specific sampling clock shift in time domain on the one hand and uses the phase rotation device to compensate the corresponding phase rotation of the remaining clock shift in frequency domain on the other hand. Among them, the correction of the specific sampling clock shift is achieved by adjusting the generator generating the clock required for sampling or removing prestage device with a clock controller in the compensation device.

Granted: 2006-01-01
Abstract: A new method in the design for an electronic power supply for suppressing signal interference in equipment of an electronic system due to ground current in a ground loop is provided. In a power supply comprising a transformer, a primary circuit, a secondary circuit, and ground conductors, the method is done by connecting the common signal references of the primary and secondary sides to the ground conductors through a capacitor and an inductor connected in series. The added capacitor is to reject DC and low frequency noise and interference. The added inductor is to reject high frequency noise and interference. Most noise and interference signals therefore cannot pass through the formed paths. As a result, the degree of signal interference problem is greatly reduced.
