Patent ID: 7898325

Claim:
An amplifier circuit of a receiver for receiving a signal in a wireless network, the amplifying circuit comprising: an amplifier comprising an amplifying transistor and a bypass transistor, the amplifying transistor having a gate connected to an input for receiving the signal and a source/drain connected to a voltage source through an inductance, and the bypass transistor having a gate connected to a control signal for activating the bypass transistor in a bypass mode and a source/drain connected between the voltage source and the source/drain of the amplifying transistor in parallel with the inductance; and a switch connected in parallel with the amplifier between the input and an output, the switch being configured to activate in the bypass mode, enabling the received signal to bypass the amplifier, wherein, in the bypass mode, a voltage at the source/drain of the amplifying transistor is lower when the bypass transistor is activated than when the bypass transistor is not activated, the lower source/drain RF voltage reducing unwanted harmonics from the amplifier.
