Abstract

A CMOS voltage to current converter is proposed which is based on a cross-coupled class AB topology. Thanks to its high-linearity and high-frequency performance, the circuit can be used in high-frequency applications such as mixers, IF amplifiers and filters, etc., where linearity is one of the most critical performance parameters. When the proposed circuit is compared with other voltage to current converters such as the source-coupled pair a much higher linearity is achieved at the same power consumption
