Abstract:

A rectifier includes a first input and a second input that receive an unrectified signal, a first circuit portion including a first transistor coupled to the second input, a second circuit portion including a second transistor coupled to the first input, a third circuit portion including a third transistor coupled to the first input, a fourth circuit portion including a fourth transistor coupled to the second input. The first, second, third, and fourth circuit portions are operable to convert the unrectified signal into a rectified signal. The rectifier includes a first adjustment circuit coupled to a gate of the third transistor, and a second adjustment circuit coupled to a gate of the fourth transistor. The first adjustment circuit and the second adjustment circuit are configured to control a dead time between an on-state of the third transistor and an on-state of the fourth transistor.
