Patent ID: 6970390

Claim:
An amplifier circuit, comprising: at least two line rails for receiving a differential voltage signal which will cause one of the at least two line rails to be at a higher potential relative to the other line rail which will be at a lower potential; first and second transistor circuits, each containing at least two switching transistors individually assigned to the at least two line rails, wherein the first transistor circuit is activated by a first switching signal in order to pull the line rail at the lower potential down to a defined low logic potential via the switching transistor assigned to that line rail, the second transistor circuit is activated by a second switching signal in order to pull the line rail at the higher potential up to a defined high logic potential via the switching transistor assigned to that line rail, and all the transistors of the at least two transistor circuits are field effect transistors (FETs) of the same conduction type; and for each of the two switching transistors of the second transistor circuit, a pump circuit assigned thereto which, upon activation of the second transistor circuit, boosts the gate of the switching transistor which is assigned to the line rail at the higher potential to a potential which is higher than the defined high logic potential by at least the amount of its threshold voltage.
