Abstract
The present disclosure relates to a circuit unit, a logic circuit, a processor, and a computing apparatus. A circuit unit is provided, including: an output terminal (OUT); an output stage (105), configured to provide an output signal to the output terminal; a first node (A), to which an input of the output stage is connected; and a feedback stage (107) that receives the output signal at the output terminal and selectively provides feedback to the node. A logic circuit is further provided, including an input stage that receives a signal input, and the circuit unit. The first node receives a signal based on an output of the input stage.
Claims20
A circuit unit, including:
- an output terminal;
- an output stage, configured to provide an output signal to the output terminal;
- a first node, wherein an input of the output stage is connected to the first node;
- and
- a feedback stage that receives the output signal at the output terminal and selectively provides feedback to the first node,
- wherein the feedback stage operates based on clock signals and an enable signal, and
- wherein the enable signal is set such that:
- when the enable signal is valid, the feedback stage can provide feedback based on the clock signals and the output signal;
- and when the enable signal is invalid, the feedback stage presents a high impedance state and therefore does not provide feedback, and the circuit unit operates as a dynamic latch or a dynamic flip-flop.
