Patent ID: 8000067

Claim:
A low noise amplifier, comprising: a radio frequency input; an electrostatic discharge protection circuit including: a pair of diodes each having a first and a second terminal; a first diode of the pair having a first terminal coupled to the radio frequency input and a second terminal directly coupled to a low voltage supply; and a second diode of the pair having a second terminal coupled to the radio frequency input and a first terminal directly coupled to the low voltage supply; and an electrostatic discharge clamp directly coupled between a high voltage supply and the low voltage supply so as to provide a discharge path between the high voltage supply and the low voltage supply during an electrostatic discharge event, wherein the electrostatic discharge protection circuit is operable to float the low voltage supply and to shunt: the radio frequency input to high voltage supply positive discharge pulse using the second diode and the electrostatic discharge clamp, and the radio frequency input to high voltage supply negative discharge pulse using the first diode and the electrostatic discharge clamp.
