[ 1 ] - Improving Linearity of CMOS Variable-gain Amplifier Using Third-order Intermodulation Cancellation Mechanism and Intermodulation Distortion Sinking Techniques

This paper presents an improved linearity variable-gain amplifier (VGA) in 0.18-µm CMOS technology. The lineari­ty improvement is resulted from employing a new combinational technique, which utilizes third-order-intermodulation (IM3) cancellation mechanism using second-order-intermodul­ation (­IM2) injection, and intermodulation distortion (IMD) sinking techniques. The proposed VGA gain cell co...
