Abstract
A signal amplifier includes one or more driver stage amplifiers and a power stage amplifier. The one or more driver stage amplifiers are connected in series. The one or more driver stage amplifiers and the power stage amplifier are connected to the same power supply, such that each of the at least one driver stage amplifier forms a loop with the power stage amplifier. The signal amplifier can further include a wave trap unit configured to block an oscillation frequency in the loop. One terminal of the wave trap unit is connected to the loop. The other terminal of the wave trap unit is grounded.
