Patent ID: 8081409

Claim:
An embedded bridge rectifier, applied to the interior of an integrated circuit, for receiving an input alternating current (AC) signal and generating an output direct current (DC) signal, comprising: a first PMOS transistor, the gate and the source of the first PMOS transistor being shorted together; a first NMOS transistor, the gate and the source of the first NMOS transistor being shorted together, wherein the drains of the first NMOS transistor and the first PMOS transistor are connected at a first pad of the integrated circuit; a second PMOS transistor, the gate and the source of the second PMOS transistor being shorted together, wherein the sources of the first PMOS transistor and the second PMOS transistor are connected at a first output node of the integrated circuit; and a second NMOS transistor, the gate and the source of the second NMOS transistor being shorted together, wherein the drains of the second NMOS transistor and the second PMOS transistor are connected at a second pad of the integrated circuit and the sources of the first NMOS transistor and the second NMOS transistor are connected at a second output node of the integrated circuit; wherein the input AC signal is applied to the first pad and the second pad and the output DC signal is generated between the first output node and the second output node, and wherein the voltage of the first output node is greater than that of the second output node.
