Patent ID: 8159844

Claim:
A full-wave rectifying device, comprising: a first rectification module comprising two first rectification units, wherein each of the first rectification units comprises: a first transistor comprising a first drain, a first source, a first gate and a first substrate, and a second transistor comprising a second drain, a second source, a second gate and a second substrate, the first source being connected to the first substrate to form a first connection node, the second drain being connected to the second gate to form a second connection node, and the first drain, the first gate, the second source and the second substrate being connected to one another to form a third connection node; and a second rectification module comprising two second rectification units, wherein each of the second rectification units comprises a third transistor comprising a third drain, a third source, a third gate and a third substrate, and a fourth transistor comprising a fourth drain, a fourth source, a fourth gate and a fourth substrate, the third source being connected to the third substrate to form a fourth connection node, the fourth drain being connected to the fourth gate to form a fifth connection node, and the third drain, the third gate, the fourth source and the fourth substrate being connected to one another to form a sixth connection node; wherein the second connection node of the second first rectification unit is connected to the first connection node of the first first rectification unit, and the fourth connection node of the second second rectification unit is connected to the fifth connection node of the first second rectification unit.
