A programmable voltage to current converter is described that is highly linear and may be implemented with a compact MOSFET switching network. With this design, the power consumption is also minimized. The programmable voltage to current converter comprises a switch network comprising one or two sets of N switches and one or two sets of N resistors, an op amp, and a current buffer MOSFET. The output current is independent of the characteristics of the one or two sets of N switches. To implement a single-ended converter, the switch network comprises one set of N resistors and one set of N switches. To implement a differential-ended converter, the switch network comprises two sets of N resistors and two sets of N switches. |
