1. A frequency doubler, comprising:
- a non-overlapping signal generation circuit configured to receive a first signal and a first control signal and generate a first and a second non-overlapping signal, each of the first and second non-overlapping signals having a frequency of the first signal, wherein an average of a duty cycle of the first non-overlapping signal and a duty cycle of the second non-overlapping signal is determined by the first control signal;
a combination circuit configured to receive and combine the two non-overlapping signals to generate a frequency-doubled signal.

20. A method, comprising:
-
receiving a first signal with a frequency doubler, the frequency doubler including; a non-overlapping signal generation circuit configured to receive a first signal and a first control signal and generate a first and second non-overlapping signals, each of the first and second non-overlapping signals has a frequency of the first signal, an average of a duty cycle of the first non-overlapping signal and a duty cycle of the second non-overlapping signal is determined at least partly by the first control signal; a combination circuit configured to receive and combine the two non-overlapping signals to generate a frequency-doubled signal; doubling a frequency of the first signal with the frequency doubler. - View Dependent Claims (21, 22)
