20080218241 | DIFFERENTIAL OUTPUT CIRCUIT WITH REDUCED DIFFERENTIAL OUTPUT VARIATION - In a differential output circuit, a second amplifier has a positive terminal connected to a second fixed potential and a negative terminal to a fifth switch at a first terminal. First and second switches are connected at a point connected to the fifth switch at a second terminal and to a first load. Third and fourth switches are connected at a point connected to the fifth switch at a third terminal and to a second load. The second terminal is connected to the first terminal when the second and third switches turn on. The third terminal is connected to the first terminal when the first and fourth switches turn on. | 09-11-2008 |
20090189671 | Method and Apparatus for Improvement of Matching FET Currents Using a Digital to Analog Converter - A method and apparatus to equalize currents on a matching pair of FETs having sources connected together on a silicon on insulator semiconductor chip, or other chip wherein FET bodies can be individually biased. During a determination period, functional inputs coupled to the gates of the matching pair of FETs are short circuited, and a DAC adjusts a first body voltage of a first FET in the matching pair of FETs relative to a second body voltage of a second FET in the matching pair of FETs until a currents in the first FET and the second FET are equal, within resolution of the DAC's voltage granularity. A proper DAC control value is stored and applied to the DAC following the determination period when the short circuit is removed from the functional inputs. | 07-30-2009 |
20090322403 | MULTIPLE-PHASE, DIFFERENTIAL SAMPLING AND STEERING - Methods and systems to controllably steer multiple phases of a differential signal, including to generate a differential current in response to a differential voltage, to controllably steer the differential current between multiple output circuits in response to corresponding control signals, which may be out of phase with respect to one another, and to generate multiple corresponding outputs corresponding to the multiple steered phases of the current. A differential input circuit and a current steering circuit may be common to multiple output circuits, and a common offset compensation may be provided to compensate for a substantial portion of offset associated with the multiple outputs. | 12-31-2009 |

20120139608 | Multiplexer - A multiplexer is provided. The multiplexer includes an output coupled to a complementary driving unit and a plurality of switch circuits. Each switch circuit includes a channel unit and two switches. The two switches respectively conduct two input signals to a channel end of the channel unit during different switch conduction periods, and the channel unit conducts the channel end to an output end during a channel conduction period. The switch conduction period of the first switch in the first switch circuit equals the switch conduction period of the second switch circuit, the switch conduction period of the second switch in the second switch circuit equals the switch conduction period of the first switch circuit, and the first and second switches are coupled to the same input signal. | 06-07-2012 |
