Systems and methods for signal sampling using a sampling array

A method comprising:

• obtaining a sample of a signal from a capacitive sampling array having an input interface, an output interface, and capacitive sampling channels connected in parallel between the input interface and the output interface, wherein each capacitive sampling channel has a channel-specific capacitor having a channel-specific capacitance;
• selecting a capacitive sampling channel from the capacitive sampling array for a subsequent sampling instance in response to the sample;
• and
• controlling the capacitive sampling array to sample the signal in the subsequent sampling instance using the selected capacitive sampling channel.

A method for operating a system that samples an input signal, the method comprising:

• selecting capacitive sampling channels with large channel-specific capacitance from a capacitive sampling array to sample portions of a signal that have low magnitude;
• and
• selecting capacitive sampling channels with small channel-specific capacitance from the capacitive sampling array to sample portions of the signal that have high magnitude;
• wherein the capacitive sampling array includes an input interface to receive the signal, an output interface, and capacitive sampling channels connected in parallel between the input interface and the output interface, wherein each capacitive sampling channel has a channel-specific capacitor having a channel-specific capacitance;
• and
• wherein the large channel-specific capacitance has larger capacitance than the small channel-specific capacitance, and the portions of the signal that have low magnitude have lower magnitude than the portions of the signal that have high magnitude.
