A Voltage-to-Current converter includes a current mirror having first and second poles, a first transistor coupled between the first pole of the current mirror and a low voltage through a first resistor, a second transistor coupled between the second pole of the current mirror and a low voltage through a second resistor wherein the second resistor is substantially identical with the first resistor, and wherein the output current is dependent on resistance of the first resistor, the input voltage signal applied to the gate of the first transistor, and a reference voltage signal applied to the gate of the second resistor.
