Techniques for Reducing Duty Cycle Distortion in Periodic Signals |
摘要 |
A transmitter circuit is operable to provide an output signal in response to a first periodic signal. A multiplexer circuit is operable to provide a second periodic signal as a selected signal during a first phase of operation. The multiplexer circuit is operable to provide the output signal of the transmitter circuit as the selected signal during a second phase of operation. A sampler circuit is operable to generate first samples of the selected signal during the first phase of operation. The sampler circuit is operable to generate second samples of the selected signal during the second phase of operation. A duty cycle control circuit is operable to adjust a duty cycle of the first periodic signal based on the first and the second samples. |
