20150185747 | LDO REGULATOR WITH IMPROVED LOAD TRANSIENT PERFORMANCE FOR INTERNAL POWER SUPPLY - A voltage regulator includes a feedback regulation loop and a drive transistor configured to source current to a regulated output. A transient recovery circuit is coupled to the voltage regulator circuit and includes a first transistor coupled to source current into a control terminal of the drive transistor, wherein the source current is in addition to current sourced in response to operation of the feedback regulation loop. The first transistor is selectively actuated in response to a drop in voltage at the regulated output. The transient recovery circuit further includes a second transistor coupled to sink current from the regulated output. The sink current has a first non-zero magnitude in the quiescent operating mode of the regulator circuit. In response to an increase in voltage at the regulated output, the operation of the second transistor is modified to increase the sink current to a second, greater, non-zero magnitude. | 07-02-2015 |
20150185754 | TEMPERATURE AND PROCESS COMPENSATED CURRENT REFERENCE CIRCUITS - A reference current path carries a reference current. A first transistor is coupled to the reference current path. A second transistor is also coupled to the reference current path. The first and second transistors are connected in parallel to carry the reference current. The first transistor is biased by a first voltage (which is a bandgap voltage plus a threshold voltage). The second transistor is biased by a second voltage (which is a PTAT voltage plus a threshold voltage). The first and second transistors are thus biased by voltages having different and opposite temperature coefficients with a result that the temperature coefficients of the currents flowing in the first and second transistors are opposite and the reference current accordingly has a low temperature coefficient. | 07-02-2015 |
