Power amplification device |
摘要 |
A power amplification device configured to switching-amplify a high-frequency input signal and output a switching-amplified signal. The device includes a feedback circuit configured to output a feedback signal including a portion of the switching-amplified signal; a subtractor configured to output an error signal indicating a difference between the input signal and the feedback signal; a comparator configured to compare the error signal with a threshold voltage and generate an on/off pulse signal based on a result of the comparison; a one-shot circuit configured to be set in an on-state for a time period using a rising timing of the pulse signal as a trigger; and an amplifier configured to switching-amplify the input signal by a logical OR between the generated on/off pulse signal and an output signal from the one-shot circuit, and output the switching-amplified signal. |
