ABSTRACT:
Disclosed is a rectifier circuit which utilizes field effect transistors, and which includes current sensing resistors to adjust the drive to the field effect transistors to avoid forward biasing the intrinsic bipolar transistor in the field effect transistors to thereby avoid injecting current into the substrate where the field effect transistors are formed on a common substrate. In addition, the current sensing resistors provide a fast startup, which is achieved both in the case where the field effect transistors are formed on a common substrate as well as those implementations where the field effect transistors do not share a common substrate. Current limiting resistors are also included to prevent overloading the field effect transistors and injecting current into the substrate when the field effect transistors share a common substrate.
