The high voltage output module includes a plurality of stacked transistors, and receives an input control signal able to turn on/off the current stimulator and a first voltage. A second voltage is generated by adding the voltages output by all the transistors to the first voltage and then output to the voltage control module. The voltage control module outputs a voltage control signal able to stabilize the stimulus current for the load according to the second voltage and the load impedance variation. The charge pump regulates the first voltage according to the voltage control signal, and outputs the regulated first voltage to the high voltage output module.

    摘要: The disclosure relates to a load-adaptive bioelectrical current stimulator, which comprises a current output module, an adaptation module and a control module. The current output module generates a stimulus current to an electrode. The adaptation module detects the electrical status of the stimulus current passing through the electrode and generates a feedback signal to the control module. According to the feedback signal, the control module controls the current output module to stabilize the output status of the stimulus current adaptively. Thereby, the load-adaptive bioelectrical current stimulator can use the feedback control mechanism to regulate the value of the stimulus current to adapt to variation of load impedance.

    摘要: Self-triggered Multi-finger SCRs used in ESD protection circuitry capable of turning on all SCR fingers of the multi-finger SCRs include a first source, a second source, N SCR units, (N−1) diodes, and N resistors. Each of the N SCR units includes a first node, a second node coupled to the second source, and a trigger node. An nth diode of the (N−1) diodes is coupled between a first node of an nth SCR unit and a trigger node of an (n+1)th SCR unit. An nth resistor is coupled between the first node of the nth SCR unit and the first source, wherein n and N are integers. The (N−1) diodes can be replaced by directly coupled the first node of the nth SCR unit to the trigger node of the (n+1)th SCR unit when a trigger pulse is applied at the trigger node of a first SCR unit.
