SIGNAL SAMPLING WITH OFFSET CALIBRATION

Abstract:

Methods, systems, and devices for signal sampling with offset calibration are described. For example, sampling circuitry may include an input pair of transistors where input signals may be provided to gate nodes of the transistors, and an output signal may be generated based on a comparison of voltages of drain nodes of the transistors. In some examples, source nodes of the transistors may be coupled with each other, such as via a resistance, and each source node may be configured to be coupled with a ground node. In some examples, a conductive path between the source nodes may be coupled with one or more switching components configurable for further coupling of the source nodes with the ground node. In some examples, enabling such switching components may add an electrical characteristic (e.g., capacitance) to the conductive path between the source nodes, which may be configurable to mitigate sampling circuitry imbalances.
