| 20120139604 | PULSE GENERATION CIRCUIT - A DC source generates a DC voltage between a positive electrode and a negative electrode. An inductive element and a parallel-connected switch-circuits unit are provided in a conductive path extending from the positive electrode to the negative electrode. The parallel-connected switch-circuits unit includes a plurality of switch circuits connected in parallel with one another. The switch circuit opens and closes the conductive path in accordance with a drive signal inputted from a drive circuit. The drive signal causes the plurality of switch circuits to successively perform an ON operation in which the conductive path is closed and then opened. A pulse voltage generation period in which a pulse voltage occurs in the inductive element continuously follows an ON period which is a duration from when the conductive path is closed to when the conductive path is opened. | 06-07-2012 |
| 20120286842 | PULSE GENERATOR AND METHOD OF DISPOSING PULSE GENERATOR - The semiconductor switching device of a switch circuit is disposed in an environment having a relatively low temperature, and a transformer is disposed in an environment having a relatively high temperature. A conduction path extends from a first DC input terminal to a second DC input terminal. An inductor is inserted in a section from a first branch to a second branch in the conduction path, and the switch circuit is inserted in a portion other than the section of the conduction path. A first transmission wire of a transmission line electrically connects the first branch and a first input terminal of a primary winding to each other. A second transmission wire of the transmission line electrically connects the second branch and a second input terminal of the primary winding to each other. The excitation inductance of the primary winding is higher than the excitation inductance of the inductor. | 11-15-2012 |
| 20130135024 | PULSE TRANSFORMER DRIVER - Methods, systems, and devices are described for providing a communication system for handling pulse information. Embodiments of the invention provide a pulse shaping unit operable to avoid saturation of the pulse transformer, while being easily incorporated into IC processes. Some embodiments of the pulse shaping unit provide a two-to-three level driver unit for converting a two-level input voltage signal to a three-level driver signal for driving a pulse transformer. Other embodiments of the pulse shaping unit provide components configured to differentially drive a pulse transformer, effectively converting a two-level input voltage signal to a three-level driver signal. | 05-30-2013 |
| 20130328608 | Architecture for Adjusting Natural Frequency in Resonant Clock Distribution Networks - An inductor architecture for resonant clock distribution networks is proposed. This architecture allows for the adjustment of the natural frequency of a resonant clock distribution network, so that it achieves energy-efficient operation at multiple clock frequencies. The proposed architecture is primarily targeted at the design of integrated inductors and exhibits relatively low area overheads. Such an architecture is generally applicable to semiconductor devices with multiple clock frequencies, and high-performance and low-power clocking requirements such as microprocessors, ASICs, and SOCs. Moreover, it is applicable to the binning of semiconductor devices according to achievable performance levels. | 12-12-2013 |
| 20140062566 | TRANSITIONING BETWEEN RESONANT CLOCKING MODE AND CONVENTIONAL CLOCKING MODE - A resonant clock network includes an inductor coupled to the clock network through a plurality of switches. When the clock network enters resonant mode, the turn-on of the switches to couple the inductor to the clock network is staggered. The clock network may be formed of multiple regions, each with its own inductor and switches. The turn-on of switches of each region may be staggered with respect to the turn-on off the switches of the other regions as well as to the turn-on of switches within a region. In addition to staggering the turn-on of the switches when entering the resonant mode, the switches may be turned off in a staggered manner when exiting the resonant mode of operation. | 03-06-2014 |
