Rectifier circuit

A half-wave n-times voltage rectifier for rectifying a voltage to a half-wave n-times voltage, comprising:

• a rectifier circuit for rectifying a voltage, which includes a first transistor and a second transistor, wherein:
• the first transistor includes a first node and a second node, the first node serving as a drain and source connected to a first terminal, the second node serving as a drain and source connected to a second
• terminal, the first terminal receiving the voltage, the second terminal outputting a rectified voltage;
• the second transistor including a source connected to the second node, and a gate and drain connected to a gate of the first transistor;
• and
• a bias voltage is inputted to the gate of the second transistor so that the second transistor is always in on state.
