Abstract: An SR latch circuit with single gate delay is provided. The circuit has an an enable input and an SR latch. There is first input stage having an input for receiving a set input and having an output for producing a first component of the SR latch circuit output, the first input stage having only one transistor that receives the enable input, the first input stage becoming transparent while enabled, the first input stage having a single gate delay between the input of the first input stage and the output of the first input stage. There is a second input stage having an input for receiving a reset input and having an output for producing a second component of the SR latch circuit output, the second input stage having only one transistor that receives the enable input, the second input stage becoming transparent while enabled, the second input stage having a single gate delay between the input of the second input stage and the output of the second input stage.

Abstract: Receiver circuitry is disclosed that can take circuit branches offline to possibly adapt an offset value. In one embodiment, a circuit in a receiver has at least two branches. Each branch includes an adjustor to adjust the branch signal by an offset value. Selection circuitry takes one of the branches offline by selecting the output of that branch as an offline value, and by selecting the output of one or more of the other branches as a data decision value. The selection circuitry changes which branch is taken offline during the operation of the circuit. When a branch is taken offline, an offset value associated with that branch may be updated, if necessary.

Abstract translation: 公开了可以使电路分支离线以适应偏移值的接收器电路。 在一个实施例中，接收器中的电路具有至少两个分支。 每个分支包括调整器，以通过偏移值来调整分支信号。 选择电路通过选择该分支的输出作为离线值，并通过选择一个或多个其他分支的输出作为数据判定值，使其中一个分支离线。 选择电路在电路运行期间改变哪个分支脱机。 当分支脱机时，如果需要，可以更新与该分支相关联的偏移值。
