    Abstract: A logic signal transmission circuit includes a driving circuit, an isolation section, and a latch section. The driving circuit converts an input digital signal to a differential digital signal. The isolation section blocks direct current and passes the differential digital signal. The latch section has even numbers of inverters which are connected in a loop and output a logic signal by turning ON and OFF a power supply voltage in a complementary manner. An input impedance of the latch section is set so that when a logic level of the differential digital signal changes, a transient voltage inputted through the isolation section to the latch section changes across a threshold voltage of the latch section. When the transient voltage changes across the threshold voltage, a logic level of the logic signal changes.

  • Patent number: 7579896
    Abstract: A method and apparatus are disclosed for generating multiple separate analog signals using a single microcontroller output pin. The microcontroller generates a waveform that is used to concurrently generate multiple separate analog signals. The microcontroller outputs a waveform that includes a first signal from one of the microcontroller's output pins. The first signal is used to produce a first analog signal. The microcontroller then outputs a delineating signal, as part of the waveform, from the microcontroller's output pin. The delineating signal indicates the start of a next signal in the waveform. The microcontroller then outputs a second signal, as part of the waveform, from its output pin. The second signal is used to produce a second analog signal. The waveform includes the first signal that is followed by the delineating signal that is followed by the second signal.

  • Publication number: 20090072881
    Abstract: There is provided a system using an analog receptor for passage of signals (either input or output of signals). The system includes a signal switch device coupled to the analog receptor; and a microcontroller controlling the signal switch device, the microcontroller being for the control of the signal switch device when a determination of a type of input signal through the analog receptor is received by the microcontroller. It is advantageous that the signal switch device allows connection to an analog circuit unless the microcontroller causes the signal switch device to divert digital signals input through the analog receptor to the microcontroller. The system may be used in an apparatus such as, for example, a media player docking station, a media player, a PDA, a portable games console, and a mobile phone. It is preferable that the analog circuit may be selected from for example, an operational amplifier, an analog-to-digital convertor, or a digital-to-analog convertor.
