Abstract: A data converter can include a resistor network, a switch network connected to the resistor network and having a plurality of switch circuits, each with an NMOS and a PMOS switch transistor, and a voltage generator to generate a drive voltage for driving a gate of at least one of the NMOS or PMOS switch transistors of at least one of the switch circuits. The voltage generator can include first and second pairs of transistors, each pair having connected control terminals and being connected to a second NMOS or PMOS transistor, a first or second resistor, and the other pair of transistors. The first and second resistors can have substantially equal resistance values. A ratio of width-to-length ratios of the second NMOS to PMOS transistors can be substantially equal to such a ratio of the switch circuit NMOS to PMOS transistors.
