Abstract:
1. A voltage-to-current converter, for converting an input voltage to generate an output current, comprising: an input terminal, for receiving the input voltage; a resistor, coupled to the input terminal, wherein the resistor is a variable resistor mirror coupled to a current controlled oscillator; a current mirror, coupled to the resistor, for mirroring a reference current to generate a mirrored current, wherein the reference current is formed according to at least a current flowing through the resistor, and the mirrored current is used for generating the output current; a first current source, for supplying a first current to the current mirror; and a second current source, for supplying a second current to the current mirror; wherein the first current is greater or equal to the second current.
