摘要： A method and apparatus that dynamically control an amount of offset current generated by a keeper device are provided. Further, a method and apparatus that use a temperature-controlled keeper device to dynamically optimize an evaluation performance of a dynamic circuit are provided. In particular, when IC temperature is relatively high, i.e., there is increased current leakage in the dynamic circuit, an amount of offset current output by the temperature-controlled keeper may be increased, thereby preventing a dynamic node of the dynamic circuit from being discharged, or otherwise adversely affected, by the increased current leakage. Alternatively, when the IC temperature is relatively low, i.e., there is decreased current leakage in the dynamic circuit, the amount of offset current output by the temperature-controlled keeper may be decreased, thereby ensuring that the offset current is not so large that it severely degrades the evaluation performance.

摘要： An invention is provided for an adaptive keeper circuit. The adaptive keeper circuit includes a first keeper transistor having a first terminal in electrical communication with a power supply and a second terminal in electrical communication with an internal dynamic node. In addition, a second keeper transistor is included that is configured in parallel to the first keeper transistor. The second keeper transistor also has a first terminal in electrical communication with the power supply. The second keeper transistor can be added to the first keeper transistor using a feedback bit line, which is configured to control current flow between the second keeper transistor and the internal dynamic node based on a state of the feedback bit line. The state of the feedback bit line is based on a process corner characteristic of the die. Additional keeper transistors and corresponding feedback bit lines can be added to the keeper circuit to increase flexibility.

摘要： A digital delay-locked loop has been discovered having a reduced area as compared to typical register-controlled delay-locked loops (RDLLs) used to control strobe delay lines that provide delay to strobe signals driving asynchronous FIFOs. This result is achieved by reducing ratio computation (i.e. gear logic) circuitry of the RDLL. A master delay line receives a control code to delay a reference clock by one clock period. A slave delay line receives the control code to delay a strobe signal by a predetermined fraction of the clock period. The master delay line may include individual sections responsive to the control code which effectively delay a signal by a portion of the clock period, the delay having a fixed relationship to a delay associated with individual sections of the slave delay line.
摘要翻译：与典型的寄存器控制的延迟锁定环（RDLL）相比，已经发现数字延迟锁定环路具有减小的面积，用于控制对驱动异步FIFO的选通信号提供延迟的选通延迟线。该结果通过减少RDLL的比率计算（即齿轮逻辑）电路来实现。主延迟线接收一个控制码，将参考时钟延迟一个时钟周期。从属延迟线接收控制码，以将选通信号延迟预定分钟的时钟周期。主延迟线可以包括响应于控制代码的各个部分，其有效地将信号延迟了时钟周期的一部分，该延迟具有与从属延迟线的各个部分相关联的延迟的固定关系。
