Abstract
At least some embodiments are directed to a system that comprises a differential switch network comprising first and second output nodes, first and second transistors coupled to the network, and first and second resistors coupled to the first and second transistors. The DAC also comprises a voltage source coupled to the first resistor and a ground connection coupled to the second resistor. The DAC further includes a capacitor coupled to the first and second transistors and to the second resistor.
