Patent ID: 7948296

Claim:
A synchronous rectifier comprising: a MOSFET device with a drain, a source and a gate; at least one negative feedback circuit coupled to said drain of said MOSFET device; at least one positive feedback circuit coupled to said source of said MOSFET device; at least one control circuit coupled to said at least one negative feedback circuit and said at least one positive feedback circuit, said control circuit operable to provide a gate control signal; said gate control signal being applied to said gate of said MOSFET device and operable to maintain a rectifying operation; a reference voltage coupled to at least one resistor, said at least one resistor located within said positive feedback circuit between said MOSFET device and said control circuit, said coupling contributing to a closed loop control having linear gain whereby said MOSFET device emulates an ideal diode; and a frequency compensation network connected to said control circuit.
