Abstract: A device includes a first compensation circuit configured to adjust an analog front end (AFE) output to generate a first adjusted AFE output, a first data slicer configured to output a first voltage based on the first adjusted AFE output. The first compensation circuit includes a first path between a voltage source and a ground, including a first transistor, a first adjustable current source, a first input voltage node configured to receive the AFE output, and a first output voltage node coupled to the first data slicer, a second path between the voltage source and the ground, including a second transistor, a second adjustable current source, a second input voltage node configured to receive the AFE output, and a second output voltage node coupled to the second data slicer, and a configurable resistance resistor and a configurable capacitance capacitor coupled in parallel across the first path and the second path.

Abstract: An on-chip scope and a method for operating the on-chip scope. The on-chip scope includes a provision for operating in one of two states, the effects of voltage offsets being different in the two states. A first voltage is measured in the first state, a second voltage is measured in the second state, and the two measurements are combined to generate a voltage estimate in which the effects of voltage offsets are reduced.

Abstract: A comparator. The comparator includes two back-to-back inverters, a differential pair, and a first common mode compensation transistor. The differential pair has two outputs configured to receive respective series currents from, or supply respective series currents to, the back-to-back inverters. The first common mode compensation transistor is configured to supply a compensating current to, or draw a compensating current from, a first output of the two outputs of the differential pair.

Abstract: A data slicer may include an input transistor configured to generate an internal output voltage based on an input voltage at an input node. An output node may be configured to output an output voltage based on the internal output voltage, and a feedback transistor may be configured to adjust the internal output voltage based on a correction voltage corresponding to output of the output node in a previous cycle.
