Abstract
The present invention discloses a mixer using a replica voltage-current converter, and more particularly a mixer using the replica voltage-current (V-I) converter of the present invention, which feedbacks the output current of the replica voltage-current converter using an additional amplifier so as to improve the linearity thereof by the gain of the amplifier because the conventional mixer operating at a high speed dissipates a lot of electrical power to have low output impedance.
