    Abstract: A logic device includes a data input, a scan test input, a clock demultiplexer, and a master latch. The clock demultiplexer is responsive to a clock input to selectively provide a first clock output and a second clock output. The master latch is coupled to the data input and to the scan test input and includes an output. The master latch is responsive to the first clock output of the clock demultiplexer and the second clock output of the clock demultiplexer to selectively couple the data input or the scan test input to the output.

    Abstract: Techniques are described that embed a digital assisted regulator with an LDO regulator on a chip without requiring a capacitor external to the chip and to regulate a voltage without undershoot. The digital assisted regulator responds to information regarding operation of the LDO regulator and to a signal that provides advance notification of a load change. When the advance notification signal is received, the digital assisted regulator pulls a circuit's supply voltage up to a chip's incoming supply voltage. When the correct operating voltage has been reached and any undershoot problem removed, the digital assisted regulator balances the current it provides with the current provided by the LDO regulator, to allow a quick response time for other load changes. Also, bandwidth of an LDO regulator may be expanded by use of an advance notice signal to increase bias current of an LDO output device to meet an upcoming load change.
