A dynamic flip-flop circuit which outputs an output signal on which a digital data signal is reflected based on a clock, includes: a first control stage configured to output a signal having a level inverted from that of the digital data signal within a period within which the clock has a second level; a second control stage configured to output a signal of a first level within the period within which the clock has the second level and a signal of a level within another period within which the clock has the first level; a third control stage configured to output an output signal of the first level within a period within which the signal outputted from the second control stage has the second level; and a phase adjustment circuit configured to adjust the phase to produce a second clock and supply the second clock to the third control stage.

In receiver systems for cellular phones using the W-CDMA method, the change in DC voltage occurring when the gain of a programmable gain amplifier (PGA circuit) is switched to adjust the gain for a received signal, can be suppressed. A sample-and-hold circuit is installed containing a “sample” mode for directly outputting a signal from the PGA section and also containing a “hold” mode for outputting the electric charge of a specified voltage stored in a capacitor. This sample-and-hold circuit normally operates in “sample” mode so the output signal from the PGA section is directly output, but is operated in “hold” mode at the gain switching timing of the PGA circuit, so that the electric charge of the specified voltage stored in the capacitor is output for a specified length of time (equal to the time required for the DC voltage change to converge to a stable level).

An active filter (100) is disclosed with improved blocker signal rejection characteristics. Linear resistors, such as fixed value resistors (3, 4) are used at the input stage (72) of the filter (100) to suppress any blocker signal. A gain compensation stage (57) is added to the output stage (23) using resistors (24) fabricated with the same technology used to fabricate the input resistors (3, 4) in order to offset any gain changes associated with the input fixed value resistors (3, 4). In an exemplary embodiment, the fixed value resistors (3, 4) are fabricated using polysilicon.
摘要:
A filter circuit extracts a desired signal in the presence of interference by using a variable gain circuit whose input is the frequency converted received signal and whose output is fed through an active filter to produce the desired signal. The signal levels before and after the active filter are detected and the higher level is used to control the gain of the variable gain circuit.

An electron emission device includes an electron-supply layer formed of metal or semiconductor; an insulator layer formed on the electron-supply layer; and a thin-film metal electrode formed on the insulator layer, whereby electrons are emitted when an electric field is applied between the electron-supply layer and the thin-film metal electrode. The insulator layer and the thin-film metal electrode have at least one island-like region where the thicknesses of the insulator layer and the thin-film metal electrode gradually decrease.
摘要:
A transmitting apparatus which can suppress unnecessary power consumption. An optimal signal line is selected from a plurality of signal lines (53-56) having different gains provided by respective signal amplifying devices to perform gain adjustment on a signal to be transmitted, which is supplied to an input terminal (58), so as to optimize power consumption of each signal amplifying device in accordance with a gain value, and to halt the operation of the signal amplifying device on a signal line which is not selected. Therefore, unnecessary power consumption can be suppressed.

An optical information recording medium comprises resin-recording layers respectively made of polymers each carrying a dye. The layers are laminated on a substrate in such a manner that the first and second layer in the resin-recording layers directly adjoin each other. The first polymer constructing the first layer has a solubility to be insoluble to the second solvent capable of dissolving the second polymer constructing the second layer. The second polymer has a solubility to be insoluble to a first solvent capable of dissolving the first polymer.
