<p>An amplifier includes a signal processing circuit configured to generate an orthogonal signal orthogonal to an input signal; a first D/A converter configured to convert the orthogonal signal into a first analog signal; a second D/A converter configured to convert the input signal into a second analog signal; and an analog computing circuit configured to generate a constant envelope signal based on the first analog signal from the first D/A converter and the second analog signal from the second D/A converter.</p> |
