摘要： A voltage regulator includes a first and second amplifier stage, an output stage, and a variable zero circuit. The first amplifier stage is coupled to receive a reference voltage and introduces a first pole of the voltage regulator. The second amplifier stage is coupled to the first amplifier stage and introduces a second pole of the voltage regulator. The output stage is coupled to the second amplifier stage, has an output driver, and is coupled to provide an output voltage based on the reference voltage. The variable zero circuit is coupled to the first amplifier stage, the second amplifier stage, and the output stage. The variable zero circuit provides a zero to compensate for at least one of the first pole or the second pole of the voltage regulator based on a gate to source voltage of the output driver and a drain to source voltage of the output driver.

摘要： An adaptive variable length pulse synchronizer including a state keeper circuit, an asynchronous pulse edge detection circuit, a data synchronization circuit, and a pulse edge synchronization circuit. The state keeper circuit detects a leading edge of the asynchronous pulse. The asynchronous pulse edge detection circuit detects a trailing edge of the asynchronous pulse after the state keeper circuit has detected the leading edge. The asynchronous pulse edge detection circuit further provides a pulse synchronized with a clock signal after the asynchronous pulse has been detected. The data synchronization circuit latches the asynchronous data and provides the synchronous data in response to the synchronous pulse. The pulse edge synchronization provides the synchronous ready signal after synchronous data has been provided. In one embodiment, the synchronous pulse occurs between successive rising edges of the clock whereas the synchronous ready signal is provided in response to the intermediate falling edge of the clock.

摘要： An input voltage circuit comprises an input transistor having a control electrode for receiving a variable input voltage, a voltage detection transistor having a current electrode coupled to a current electrode of the input transistor forming a first node, and a current source coupled to a second current electrode of the voltage detection transistor forming a second node. The input voltage circuit further comprises a variable voltage drop transistor having a first current electrode coupled to the first node, a control electrode coupled to the second node and a second current electrode coupled to an output node, wherein the voltage detection transistor detects a variation in the variable input voltage and provides a signal to the variable voltage drop transistor. The variable voltage drop transistor generates a voltage drop proportional to the variation in the variable input voltage to ensure a substantially constant output at the output node.

摘要： Methods and corresponding systems for buffering an input signal include outputting a first logic value in response to the input signal being below a lower threshold. A second logic value is output in response to the input signal rising above the lower threshold. Thereafter, the second logic value is maintained until the input exceeds a higher threshold and thereafter falls below the higher threshold. In response to the input signal falling below the higher threshold, the first logic value is output, and maintained at the first logic value, until the input falls below the lower threshold and thereafter rises above the lower threshold.
