    Hi, here is my circuit diagram. What I'm trying to do is connect the oscillator and charge pump to N-MOSFET to be act as a switching device.
    I follow the concept as in "diagram_2" in attachment below, but what I get is the output look like this: "diagram_1_output". I don't know what's going on here. Is that my connection wrong or what. =(
