Amplifiers with shunt switches |
摘要 |
<p>Amplifiers with shunt switches to mitigate interference are disclosed. In an exemplary design, an apparatus includes an amplifier and a shunt switch. The amplifier has an input operatively coupled to an input/output (I/O) pad of an integrated circuit (IC) chip. The shunt switch grounds the amplifier when the shunt switch is closed. The shunt switch is isolated from the I/O pad and the amplifier input. The amplifier may be a low noise amplifier (LNA) or some other type of amplifier. In an exemplary design, the shunt switch is isolated from the I/O pad by a series switch. The series switch and the shunt switch may be closed when the amplifier is disabled and may be opened when the amplifier is enabled.</p> |
