  • Patent number: 10735008
    Abstract: A comparator offset voltage self-correction circuit is disclosed. A comparator offset voltage which is caused by the semiconductor process parameter randomness also has randomness. Due to the randomness of the comparator offset voltage, a reference voltage of a parallel comparator in a parallel-conversion-type analog-to-digital converter is uncertain. If the comparator offset voltage is large, the parallel-conversion-type analog-to-digital converter may even have a functional error. The comparator offset voltage self-correction circuit provided in the present invention can correct a random offset voltage of a comparator to meet requirements.

  • Patent number: 10128830
    Abstract: A track and hold circuit comprises an input buffer amplifier, a unit gain amplifier module, a sampling switch, a drive triode and a sampling capacitor. The input buffer amplifier receives an input signal. In a track phase, the sampling switch is electrically connected to an emitter electrode of the drive triode; the input signal charges the sampling capacitor after being buffered by the input buffer amplifier, amplified without distortion by the unit gain amplifier module and driven by the drive triode. In a hold phase, the sampling switch is electrically connected to a base electrode of the drive triode; the base voltage of the drive triode is pulled down until the drive triode is cut off; electrical charges on the sampling capacitor are thereby held, causing the signal to be held on the sampling capacitor.

  • Publication number: 20140219289
    Abstract: A part of a non-default multitenant device context (MDC) is located on a member device of that forms part of a logical network device. The non-default MDC part assigns a first downlink port to a first downlink port group, assigns a first uplink port to a first uplink port group, and monitors a stacking port to another part of the non-default MDC on another member device that forms part of the logical network device. When the stacking port changes to the down state, the non-default MDC part determines if the first downlink port group and the first uplink port group are in the up state. If so, the non-default MDC part maintains the states of the ports in the first downlink port group and the first uplink port group. Otherwise the non-default MDC part makes changes so the ports in the first downlink port group and the first uplink port group are in the down state.

  • Publication number: 20140152348
    Abstract: A BiCMOS current reference circuit includes a reference core, a startup circuit, and a reference current output circuit. The reference core contains a current mirror, a positive temperature coefficient current generator, and a negative temperature coefficient current generator. The current mirror generates matching branch current. The positive and negative temperature coefficient currents were added in certain proportion to generate a reference current with zero temperature coefficient at room temperature. The startup circuit starts the reference core at power-on. The reference current output circuit proportionably outputs reference current generated by the reference core. Compared with the conventional voltage reference, the circuit uses current conveying technique, so it won't be affected by DC voltage drops of power supply network, and it features low transmission loss, good matching, excellent temperature stability, small chip size and auto-startup at power-on.
