Pre-charge circuit with differential inputs and outputs

A system comprising:

• an electronic circuit comprising:
• a differential input including a first input node and a second input node and coupled, during operation, to an input capacitor;
• a differential output including a first output node and a second output node and coupled, during operation, to an output capacitor;
• a first switch coupled between the first input node and the first output node;
• a pre-charge circuit configured to inject charge at the first output node;
• and
• a control circuit configured to:
• switch the first switch on and off;
• and
• control the pre-charge circuit to inject charge at the first output node while the first switch is off, and
• an analog-to-digital converter having a differential input that is coupled to the differential output of the electronic circuit
• wherein the output capacitor of the electronic circuit is formed by the input capacitance of the analog-to-digital converter.
