摘要：

A CMOS voltage-to-current converter with exponential characteristics is presented. The Taylor's series expansion is used for realising the exponential function. In a 0.35 mu m CMOS process, the HSPICE simulation results show a 15dB linear range with a linearity error of < +/-0.5dB. The total power consumption is < 0.8mW with +/-1.5V supply voltage. The circuit can be used in the design of a Variable gain amplifier (VGA).
