Title:
予め定められたデューティサイクル信号発生器
Document Type and Number:
Japanese Patent JP2012531837
Kind Code:
A
Abstract:
Techniques for generating a signal having a predetermined duty cycle. In an exemplary embodiment, a first counter is configured to count a first number of cycles of an oscillator signal, and a second counter is configured to count a second number of cycles of the oscillator signal, with the second number being greater than the first number. The output of the second counter is used to reset the first and second counters, while the outputs of the first and second counters further drive a toggle latch for generating the signal having predetermined duty cycle. Further aspects include techniques for accommodating odd and even values for the second number.
