Apparatus are provided for a voltage-controlled oscillator module. A voltage-controlled oscillator module comprises an input node for receiving an input voltage, a voltage-controlled oscillator, and voltage translation circuitry coupled between the input node and the voltage-controlled oscillator. The voltage translation circuitry is configured to generate a control voltage based on the input voltage and the voltage-controlled oscillator generates an oscillating signal at an oscillation frequency in response to the control voltage. Biasing circuitry is coupled to the voltage translation circuitry, and the biasing circuitry is configured to adjust the ratio of the control voltage to the input voltage.
