摘要： The present invention provides a current limit circuit apparatus, coupled with the gate of a GaN transistor. The current limit circuit comprises a diode, a first transistor, a second transistor, a first resistor, a second resistor, a third resistor and a fourth resistor. The source and the drain of the first transistor couple with the diode. The source of the second transistor couples with the gate of the first transistor. The source of the first transistor couples with the first transistor. The source of the second transistor couples with the second resistor. The third resistor couples with the fourth resistor and the gate of the first transistor. The first transistor turned off and the gate current is limited. When the current of the gate of the GaN transistor exceeds the predetermined value, the breakdown voltage is increased by limiting the gate current.

摘要： The present invention provides a high-side driver circuit including a power transistor, the first transistor, the second transistor, the second capacitor, the second diode, a start-up circuit. The start-up circuit is coupled between a resistor and the second capacitor to complete a gate driving circuit. And, the aforementioned resistor can either be the gate resistance of the power transistor or an external resistor. The design of start-up circuit enables the functionality of the bootstrap capacitor of being charged to a designate voltage level. Thus, the depletion-mode transistor can be controlled to turn on/off without a floating voltage source or a negative voltage source.

摘要： The present invention proposes a single-axis-control-input gyroscope system having imperfection compensation, which comprises a gyroscope and a state observer. The gyroscope includes a mechanical structure, and the dynamic behavior of the mechanical structure is described with a plurality of system parameters and a plurality of dynamic equations. The system parameters include a mass of the gyroscope, two main-axis spring constants, a cross-axis spring constant, two main-axis damping coefficients, a cross-axis damping coefficient and an angular velocity. The mechanical imperfections cause the system parameters to deviate from the designed values and become unknown values. The gyroscope receives a single-axis control signal and outputs a plurality of gyroscopic system dynamics. The single-axis control signal includes at least two frequency signals. The state observer is coupled to the gyroscope to receive the gyroscopic system dynamics as the inputs thereof to feed back compensations to the state observer. Thereby is estimated an angular velocity.

摘要： An MEMS gyroscope is disclosed, capable of computing the rotating angle of a DUT being attached thereto without the need to execute an off-line calibration process, of precluding the execution of an integration process, and of executing an on-line compensation process for the error introduced by the sensing circuit defect and by the mechanical structure defect of its gyroscope module. The disclosed MEMS gyroscope comprises: a gyroscope module, a sensing module coupled with the gyroscope module, and a control module couple with the gyroscope module and the sensing module, respectively. The control module receives the system dynamic of the gyroscope module sensed by the sensing module, and applies a gyroscope control method for controlling the gyroscope module and computing the rotating angle of the DUT. Moreover, the control module outputs a control signal including two extra frequency signals, to the gyroscope module, for driving the gyroscope module into operation.
