Abstract
An amplifying circuit for receiving a signal in a wireless network includes an amplifier and two switches. The amplifier includes an isolation switch having a gate connected to a control signal for activating the isolation switch transistor in a bypass mode and a source/drain connected to the input for receiving the signal and the other source/drain connected to the gate of an amplifier transistor. The amplifier also includes a bypass transistor having a gate connected to a control signal for activating the bypass transistor in a bypass mode. The bypass switch is connected in parallel with the series combination of the isolation switch and amplifier between the input and output, enabling the received signal to bypass the amplifier. In the bypass mode, the isolation switch prevents RF energy from voltage modulating the gate of the amplifier transistor gate thus reducing undesirable distortion and harmonics from the amplifier.
