1. A processing system configured to detect an input object proximate the processing system comprising:
sensor circuitry configured to:
determine that the processing system is in a low ground mass (LGM) state,
determine an object having a size exceeding the input object is proximate to a plurality of sensor electrodes, the plurality of sensor electrodes arranged in substantially orthogonal rows and columns and configured to transmit uplink signals to the input object; and
in response to the object being determined proximate to the plurality of sensor electrodes and the processing system in the LGM state,
drive a first group of the plurality of sensor electrodes with one of an inverted modulated signal or a non-inverted modulated signal, and
drive a second group of the plurality of sensor electrodes with a static non-modulated DC voltage, wherein the first group of the plurality of sensor electrodes comprises at least one row of sensor electrodes that intersect a location where the object is proximate the plurality of sensor electrodes.
