    • A method for integrating an IC and a MEMS component includes the following steps: S1) providing a SOI base (20) having a first area (21) and a second area (22); S2) fabricating an IC on the first area through a standard semiconductor process, and simultaneously forming a metal conductive layer (26) and a medium insulation layer (25c) extending to the second area; S3) partly removing the medium insulation layer and then further partly removing the silicon component layer so as to form a backplate diagram; S4) depositing a sacrificial layer (32) above the SOI base; S5) forming a Poly Sil-xGex film (33) on the sacrificial layer; S6) forming a back cavity (34); and S7) eroding the sacrificial layer to form a chamber (36) in communication with the back cavity. Besides, a chip (10) fabricated by the above method is also disclosed.

    • A controller includes a ramp signal generator and control circuitry coupled to the ramp signal generator. The ramp signal generator provides a control current through a resistive component to control energy stored in a first energy storage component. The ramp signal generator further generates a ramp signal based on the energy stored in the first energy storage component. The control circuitry adjusts a voltage at one end of the resistive component thereby controlling the control current to indicate a voltage across a second energy storage component. The control circuitry further controls a current through the second energy storage component within a predetermined range based on the ramp signal.
    • 控制器包括斜坡信号发生器和耦合到斜坡信号发生器的控制电路。 斜坡信号发生器通过电阻部件提供控制电流,以控制存储在第一能量存储部件中的能量。 斜坡信号发生器还基于存储在第一能量存储部件中的能量产生斜坡信号。 控制电路调节电阻部件一端的电压,从而控制控制电流以指示跨越第二能量存储部件的电压。 控制电路还基于斜坡信号进一步控制在预定范围内通过第二能量存储部件的电流。
