Abstract
Frequency divider circuits and architectures, and methods of implementing and using the same, are disclosed. In one embodiment, the frequency divider circuit includes a dynamic section that receives an input signal and outputs an intermediate signal that has a frequency lower than that of the input signal; and a static section that receives the intermediate signal and outputs a signal having a frequency that is lower than that of the intermediate signal. Stages in the dynamic and/or static section can be implemented using thin film transistors (TFTs). Embodiments of the present invention advantageously provide an approach that takes overcomes problems associated with the leakage and speed characteristics of TFTs.
