Title: System, apparatus and method for voltage to current conversion

Abstract: A voltage-to-current converter having improved third order distortion is disclosed herein for use in an FM radio system, particularly an FM radio system which employs a broadband input filter rather than a narrow band input filter. By cross-coupling a main amplifier with a second amplifier that produces more distortion and has a smaller g.sub.m, than the main amplifier, third order frequency peaks resulting from non-linear amplification of undesired signals can be prevented from interfering with a desired signal because the magnitude of the third order frequency peak is reduced.
