20100097047SERIES REGULATOR CIRCUIT - A low drop out series regulator circuit for generating an output voltage that does not rely on voltage feedback or require a capacitor for stable operation includes first and second current sources connected in series between a supply voltage and ground. A resistor is connected between and in series with the first and second current sources, and a reference voltage is generated across the resistor by the current from the first current source. A first transistor is connected between the ground and a first node located between the resistor and the second current source. A current mirror circuit is connected between the supply voltage and the first transistor. A current sense transistor is connected between the current mirror circuit and an output terminal. An output transistor is connected between the supply voltage and the output terminal. The output voltage generated at the output terminal is equal to the reference voltage.04-22-2010
20100072979METHOD FOR TESTING A VARIABLE DIGITAL DELAY LINE AND A DEVICE HAVING VARIABLE DIGITAL DELAY LINE TESTING CAPABILITIES - A device and a method for testing a variable digital delay line that includes multiple taps. The method includes providing, an input signal to the variable digital delay line and finding, for each tap out of a group of tested taps of the variable digital delay line, a variable delay unit configuration that provides a delay that is closest to a delay introduced by the tap; wherein the variable digital delay line and the variable delay unit belong to the same integrated circuit.03-25-2010
