In described examples, a variable-gain power amplifying technique includes: generating a first oscillating signal (400) with a network of one or more reactive components included in an oscillator; and outputting a second oscillating signal (402) via one or more taps included in the network of the reactive components. The second oscillating signal has a magnitude that is proportional to and less than the first oscillating signal. The power amplifying technique further includes selecting one of the first and second oscillating signals to use for generating a power- amplified output signal (404), and amplifying the selected one of the first and second oscillating signals to generate the power-amplified output signal (406). |
