1. An apparatus, comprising:
a first filter comprising a first amplifier, the first amplifier comprising a first resistor-capacitor (RC) feedback network coupled between an input and output of the first amplifier;
a second filter comprising a second amplifier, the second amplifier comprising a second RC feedback network selectively coupled between an input and output of the second amplifier;
a first set of one or more switching devices configured to selectively couple the first filter to the second filter, wherein the first set of one or more switching devices is configured to selectively couple inputs and outputs of the first and second amplifiers together; and
a second set of one or more switching devices configured to selectively couple the first and second RC feedback networks to capacitors of a capacitor bank.
