Abstract:
Cascode power amplifier with voltage limiter. A power amplification system can include an input transistor having an input transistor gate configured to receive a radio-frequency (RF) signal, an input transistor source coupled to a ground voltage, and an input transistor drain. The power amplification can further include an output transistor having an output transistor drain configured to output an amplified version of the RF signal, an output transistor gate coupled to a bias voltage, and an output transistor source. The power amplification system can further include a high voltage limiter coupled between the output transistor drain and output transistor gate. The high voltage limiter can be configured to prevent a gate-drain voltage of the output transistor from exceeding a high voltage threshold.
