Optimized noise suppresion for enhanced signal processing

A system, comprising:

• an input source configured to generate input signals;
• and
• an integrated circuit configured to process the input signals with respect to a first ground,
• wherein the input signals are referenced to a second ground that is coupled to the first ground, the integrated circuit including:
• a first input terminal configured to:
• receive the input signals from the input source;
• and
• receive noise signals coupled through the second ground;
• a second input terminal, coupled to the second ground, configured to receive the noise signals coupled through the second ground;
• and
• circuitry, including a differential signal converter having a first differential input terminal and a second differential input terminal, configured to:
• route the input signals and the noise signals from the first input terminal to the first differential input terminal;
• and
• route the noise signals from the second input terminal to the second differential input terminal while maintaining symmetry between an input impedance toward the first differential input terminal and an input impedance toward the second differential input terminal.
