Flyback topologies are widely used in low power applications due to the small size and low cost. To improve the efficiency via reducing the switching loss, valley switching technique is introduced and several methods to realize valley switching are analysed and compared. Besides, the matter of frequency under light load condition is described, which can be solved by valley skipping technique, whereas...
An improved radio-frequency (RF) lateral double-diffused metal-oxide-semiconductor (LDMOS) device based on Si-substrate process is proposed. The structure is characterized by a p+-buried-layer (PBL) buried under the drain in the p-substrate region. A vertical n+n−p−p+ diode formed at the drain side helps deplete the n-drift region and lengthen the lateral drift distance, thus effectively increasing...
In the era of multi-core processors, the challenge of designing a high efficient memory system is more severe than before. This paper focuses on the memory hierarchy design and implementation on a multiprocessor system. With the distributed shared memory (DSM) model, some techniques have been presented to improve the performance of traditional memory hierarchy and simplify the complexity of cache...
A novel bandgap reference for minimizing current-mirror mismatch is presented. In the proposed circuit, the small-signal current variations in the two current paths are self-compensated while in the conventional bandgap core they are multiplied. As a result, error caused by current-mirror mismatch has been much reduced in the proposed circuit. Moreover, the voltage variations caused by temperature...
