Abstract
Bias schemes for cascode power amplifiers are disclosed. In certain embodiments, a power amplifier system includes a cascode power amplifier biased by a first cascode bias voltage and that amplifies a radio frequency input signal. The power amplifier system further includes a bias voltage generation circuit including a first switch, a first cascode transmit mode bias circuit that provides the first cascode bias voltage to the cascode power amplifier through the first switch in a normal power transmit mode, a low power mode bias circuit that overrides the first cascode transmit mode bias circuit to set the first cascode bias voltage in a low power transmit mode, a second switch, and a sleep mode bias circuit that provides the first cascode bias voltage to the cascode power amplifier through the second switch in a sleep mode.
