Abstract: Techniques for a configurable analog-to-digital converter filter to ameliorate transfer function peaking or frequency response issues are provided. In an example, a front-end circuit of a processing circuit can include a resistor-capacitor filter including at least two capacitors and a switch circuit. The resistor-capacitor filter can couple an input analog signal to the processing circuit. The switch circuit can couple to a first capacitor of the at least two capacitors, and can selectively place a terminal of the first capacitor at a selected one of a plurality of distinct nodes of the resistor-capacitor filter to configure the circuit to address the peaking or frequency response issue.
