This paper presents a novel IM3 (third-order intermodulation) cancellation technique using a structured auxiliary transistor array, implemented in 180nm CMOS technology, to enhance the linearity of array amplifiers. The proposed technique applies a selective transistor-capacitor array with gate voltages and switchable branches for accurate amplitude and phase tuning of generated IM3 components. With a 180° phase difference and amplitude balance between the main and auxiliary path IM3 signals, the design improves the third-order intercept point (IIP3) performance to +11 dBm, at 1.0 to 1.1 GHz. while maintaining a gain of 22 dB. With low noise figures (NF) of 4.9 to 4.2 dB in the band. Measurement results demonstrate linearity enhancement across a wide bandwidth without high bias current or additional feedback loops. In addition, the reconfigurable nature of the auxiliary array provides flexibility to different operating conditions and frequency bands. Compared to conventional IM3 techniques, the proposed technique offers high flexibility, low power and scalability, Improved Linearity, Wideband Operation, phase compensation, gain tuning, reconfigurability, for future advanced wireless communication systems. Simulation and measurement results verify substantial IM3 suppression without degrading the amplifier core performance.
