  • Publication number: 20230094277
    Abstract: A power supply device is used to provide power to an encryption and decryption device of a security system, including a safety power supply device, which is used to supply the supply voltage according to the system voltage; a regulated voltage source, which is used to provide a regulated voltage; and a voltage selection device, which is electrically connected with the safety power supply device, the stable voltage source and the encryption and decryption device. During the startup period of the security system, or, after the startup period of the security system and the encryption/decryption device performs encryption/decryption, only the supply voltage is selected as the driving voltage of the encryption/decryption device. After the startup period of the security system and the encryption and decryption device does not perform encryption and decryption, the voltage only the regulated voltage is selected as the driving voltage of the encryption and decryption device.

  • Publication number: 20230099825
    Abstract: A power supply device is provided with a secure power supply device, a voltage detection circuit, a stable voltage source and a switch. By using the voltage detection circuit, whether a driving voltage of an encryption/decryption device is insufficient to control the on and off the switch, so as to determine whether only the secure power supply device provides a supply voltage to the encryption/decryption device as the driving voltage. Alternatively, the supply voltage of the secure power supply device and a stable voltage of the stable voltage source are provided simultaneously to the encryption/decryption device as the driving voltage. In other words, once the driving voltage drops (that is, the encryption/decryption device consumes a large current for encryption/decryption), the stable voltage source immediately provides the stable voltage to the encryption/decryption device as part of the driving voltage to ensure that the encryption/decryption device can normally work.

  • Patent number: 11601050
    Abstract: A voltage regulation system is provided. In the voltage regulation system, a frequency of a clock signal is adjusted and a pulse generator is controlled to output a pulse signal to a switch power stage circuit, to enable the switch power stage circuit to adjust an output voltage and output the adjusted output voltage to the load element. Through the aforementioned configuration, the switch power stage circuit adjusts the output voltage according to the situation of the load element, thus decreasing the power loss of the switch power stage circuit.

  • Publication number: 20230021989
    Abstract: An incremental analog-to-digital converter including a first-stage non-delay memorization element and other elements is disclosed. An ending time point of a second reset signal received by the first-stage non-delay memorization element is later than an ending time point of a first reset signal received by the other elements by at least one clock cycle, a reset duration of the first-stage non-delay memorization element is longer than a reset duration of the other element, so that the first-stage non-delay memorization element can be prevented from occurring overshoot or spike on an output thereof, and the incremental analog-to-digital converter can maintain a good signal-to-noise and distortion ratio under the condition that the internal elements has low swing limits.

  • Patent number: 11527949
    Abstract: A protection circuit is adapted to a switching-capacitor regulation circuit having a capacitor. The protection circuit comprises a current source, first and second switch circuits, and a control unit. First, the control unit turns on the second switch circuit to make a top end and a bottom end of the capacitor, and control the first switch circuit to make the current source no connect the capacitor, and then set a voltage of the top and the bottom to be a first preset voltage. Next, the control unit turns off the second switch circuit to disconnect the top end and the bottom end, and turn on the first switch circuit to flow current from the bottom end of the capacitor. When a voltage difference between the top end and the bottom end is equal to a preset initial voltage, the control unit control the first switch circuit to disconnect the current source and the capacitor; next, the control unit controls current flow in or out from the top of the capacitor based on the voltage on the top of the capacitor.

  • Patent number: 11451196
    Abstract: A dynamic comparator includes a differential amplifier stage, a switching unit and a switching charge storage unit. The switching charge storage unit includes a plurality of switching transistors, and a charge storage capacitor electrically connected to the plurality of switching transistors. When an operational mode of the dynamic comparator is switched from a comparison state to a reset state, a voltage on one of a first terminal and a second terminal of the charge storage capacitor is increased from a half of the system voltage to a system voltage, so as to implement a charge recycle effect. The dynamic comparator of the present invention can have lower power consumption and lower charge-discharge current.
