1. A method comprising:
receiving a voltage from a voltage source;
identifying transconductance parameters and resistance parameters associated with a data converter, the transconductance parameters identifying a transconductance of the data converter;
selecting a resistor from a plurality of dynamically selectable resistors based on the resistance parameters;
generating, using a programmable gain amplifier, a current based, at least in part, on the selected resistor and the received voltage; and
providing the current to the data converter.
