Abstract
Systems, methods, and devices provide sampling for data converters. Methods include receiving a voltage from a voltage source, and identifying transconductance parameters and resistance parameters associated with a data converter, the transconductance parameters identifying a transconductance of the data converter. Methods also include 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.
