摘要： Disclosed is technology related to a signal synthesis apparatus that corrects an offset between a closed loop and an open loop to output a frequency-modulated signal. The signal synthesis apparatus includes a VCO configured to modulate and output a frequency signal in response to an input voltage by including a modulation cap bank having a plurality of capacitors, an energy storage unit configured to output a voltage using stored energy, a VCO input selector configured to connect the VCO to input of the energy storage unit in the case of a closed loop mode and connect the VCO to output of the energy storage unit in the case of an open loop mode, and a digital controller configured to control an operation mode of the VCO input selector and transmit a modulation control signal for adjusting a connection state of the capacitors of the modulation cap bank to the VCO.
