摘要: Disclosed is a frequency converter including: a passive type analog multiplier configured to output a multiplication result in a current; a buffer outputting a buffering current by buffering the current of the multiplication result; and a current-voltage converter current-voltage converting the buffering current. Alternately, disclosed is a frequency converter including: a passive type analog multiplier configured to output a multiplication result in a current; a buffer outputting a buffering current by buffering the current of the multiplication result; and an integrator integrating the buffering current to output a voltage.
