Latest Patents

Shuyan Lei holds a patent titled "No-enable setup clock gater based on pulse." This patent describes systems, apparatuses, and methods for implementing a high-performance clock-gating circuit. The invention involves a first pull-down stack that receives enable and pulse signals on gates of N-type transistors, which pull down an output node when both signals are high. Additionally, a pull-up transistor coupled to the output node receives a clock signal that turns off the pull-up transistor when the clock signal is high. The design includes a first pull-up stack that receives the inverted pulse signal and the enable signal on gates of P-type transistors, ensuring the output node is high when the enable signal and inverted pulse signal are low. Furthermore, a second pull-up stack maintains a high voltage on the output node after the pulse event has ended while the clock signal remains high. A second pull-down stack also maintains a low voltage on the output node after the pulse event but while the clock remains high. This innovative design significantly improves the performance of clock-gating circuits.
