Abstract
According to an embodiment, a receiver includes a voltage controlled oscillator, a frequency-to-digital converter and an input sensitivity controller. In the voltage controlled oscillator, input sensitivity relative to a baseband signal is controlled based on an input sensitivity control signal. The voltage controlled oscillator oscillates at a frequency controlled by a voltage of the baseband signal to generate an oscillation signal. The frequency-to-digital converter performs frequency-to-digital conversion of the oscillation signal to generate a digital signal. The input sensitivity controller generates the input sensitivity control signal based on the digital signal.
Claims8
A receiver comprising:
- a voltage controlled oscillator in which input sensitivity relative to a baseband signal is controlled based on an input sensitivity control signal, and that oscillates at a frequency controlled by a voltage of the baseband signal to generate an oscillation signal;
- a frequency-to-digital converter that performs frequency-to-digital conversion of the oscillation signal to generate a digital signal;
- and
- an input sensitivity controller that generates the input sensitivity control signal based on the digital signal.
