20140312864 | LIGHT LOAD STABILITY CIRCUITRY FOR LDO REGULATOR - A linear regulator contains an additional AC-coupled feedback loop between the output of the error amplifier and the base of the pass transistor that increases the frequency of the pole at the output of the error amplifier at light load currents to at least partially offset the decreased frequency of the output pole at the lighter load currents. Thus, a desired phase margin is preserved. The AC-coupled feedback loop includes a bipolar feedback transistor connected in parallel with the pass transistor. A resistor is connected to the emitter of the feedback transistor to reduce the relative gain of the feedback transistor above light load currents. A feedback capacitor Cfb is connected between the collector of the feedback transistor and the output of the error amplifier. The negative AC feedback increases the pole frequency at the output of the error amplifier and the base of the pass transistor. | 10-23-2014 |
20140312865 | VOLTAGE GENERATOR WITH CURRENT SOURCE COMPENSATED FOR AN ERROR CURRENT OPERABLE OVER A WIDE VOLTAGE RANGE - In one embodiment, a regulator circuit for generating a regulated output voltage Vout has an error amplifier using a pair of bipolar transistors at its front end. The error amplifier compares the regulated output voltage to a reference voltage Vref. A precision current source draws a first current through a user-selected set resistance to generate the desired Vref. The regulator circuit controls a power stage to cause Vout to be equal to Vref. The base current into one of the bipolar transistors normally distorts the current through the set resistance. A base current compensation circuit is coupled to the current source to adjust the first current by a value equal to the base current to offset the base current. Therefore, Vref is not affected by the base current. The error amplifier may be in a linear regulator or a switching regulator. The compensation circuit may be used in other applications. | 10-23-2014 |
20140312866 | LINEAR REGULATOR IC WITH VERSATILE GROUND PIN - A linear regulator integrated circuit may be formed having four external terminals including a voltage input (Vin) terminal, a voltage output (Vout) terminal, a Set terminal, and an operational amplifier (op amp) power terminal. A user connects an external resistor to the Set terminal for creating a reference voltage. An op amp controls a pass (or series transistor) to cause an output voltage at the Vout terminal to equal the reference voltage. The op amp has a first power supply terminal internally coupled to the Vin terminal and a second power supply terminal coupled to the op amp power terminal. The op amp power terminal allows a user to externally couple the op amp second power supply terminal to either the Vout pin (for high voltage applications), system ground (for medium voltage applications), or another voltage (to provide additional headroom in very low voltage applications). | 10-23-2014 |

20150372938 | SYSTEM AND METHOD FOR PARTITION MIGRATION IN A MULTITENANT APPLICATION SERVER ENVIRONMENT - In accordance with an embodiment, described herein is a system and method for partition migration in a multitenant application server environment. Each resource group, or partition which includes that resource group, can be associated with a virtual target (e.g., virtual host) information that defines a target to which that resource group or partition should be targeted and deployed. A web tier component (e.g., Oracle Traffic Director) includes a routing information, which maps the virtual target for a partition to a corresponding target such as a server or cluster, so that requests for that partition are directed to the appropriate target, for example as part of one or more sessions. When a partition is migrated, session information is replicated between an original target and a new target, and the web tier component provided with a revised routing information, so that subsequent requests for that partition are directed to the new target. | 12-24-2015 |
