20080204096 | Circuit and method to convert a single ended signal to duplicated signals - A circuit to convert a single ended signal to differential signals is disclosed. The circuit has two paths with each of the two paths comprising a plurality of stages. The number of stages in each of the two paths is the same. A first path of the two paths includes a buffer stage and at least one inverter stage. A second path of the two paths includes at least two inverter stages. The buffer stage has a delay matched to that of a first inverter stage of the second path. The buffer stage comprises a first pair of transistors comprising a first transistor of a first category operatively connected to a first transistor of a second category with their channel connections being connected in series. | 08-28-2008 |
20090243683 | 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. | 10-01-2009 |
20090315602 | Single-ended to differential converter - A single-ended to differential converter is presented. The converter may be configured to convert full-swing single-ended signals to low-swing differential signals within a single-stage, thereby reducing signal distortion. The converter may include a passive network of resistive elements, for example resistors and/or metal oxide semiconductor (MOS) devices operating in a linear region. The converter may also allow for adjustable design parameters such as a common mode, differential amplitude, and an output swing. The adjustments may all be made within the single-stage of the converter. | 12-24-2009 |
20100026356 | POLARITY SWITCHING MEMBER OF DOT INVERSION SYSTEM - A polarity switching member of a dot inversion system is revealed. A first transistor and a second transistor are disposed in a P-well while a N-well is arranged in the P-well, located between the first transistor and the second transistor. The N-well includes a third transistor and a fourth transistor. One end of the third transistor is coupled to one end of the first transistor to generate a first input end and one end of the fourth transistor is coupled to one end of the second transistor to generate a second input end. The other end of the first transistor, the other end of the second transistor, the other end of the third transistor, and the other end of the fourth transistor are coupled to generate an output end. Thereby, by switching of voltage polarity of the P-well and the N-well, a larger range of output voltage difference is achieved. | 02-04-2010 |

20100176857 | APPARATUS FOR OUTPUTTING COMPLEMENTARY SIGNALS USING BOOTSTRAPPING TECHNOLOGY - Disclosed herein is an apparatus for outputting complementary signals using bootstrapping technology. The apparatus for outputting complementary signals includes a precharaged logic block, one or more output nodes, and a bootstrapping circuit block. The precharged differential logic block generates a differential signal depending on an input signal. The one or more output nodes output the complementary signals depending on the differential signal. The bootstrapping circuit block is shared by the one or more output nodes, and amplifies the complementary signals. | 07-15-2010 |
20100231278 | HIGH POWER BIPOLAR PULSE GENERATORS - A bipolar pulse generator is implemented in a simple structure while providing a high efficiency design having a relatively low total size, while still allowing access by fibers used to control a photoconductive switch that activates the generator. The bipolar pulse generator includes a stacked Blumlein generator structure with an additional transmission line connected to a load at its near end and short-circuited at its distal end. An extra transmission line is positioned between the Blumlein generator's structure and the load provides specified limited gap between positive and negative sub-pulses. The bipolar pulse generator further includes a bended Blumlein generator structure, in which an existing intrinsic “stray” transmission line is used to provide the bipolar pulse. Still further, bipolar pulse generator includes stepped transmission lines, with additional switches positioned between steps, which are charged by different voltages. | 09-16-2010 |
20120081162 | AUTOMATIC DARKENING FILTER (ADF) EYE PROTECTION DEVICE WITH IMPROVED DRIVE CIRCUITRY - Disclosed is an apparatus and methodology for operating an automatic darkening filter (ADF) eye protection device. An operating voltage is alternately applied to a pair of control terminals of an ADF device circuit in a continuing sequence where a first polarity voltage is applied to the pair of terminals and then reversed. A delay period is provided between application of the alternating polarities. In some embodiments ground potential is applied to both terminals of the pair of terminals during the delay period. | 04-05-2012 |
