Abstract

A digital built-in calibration (BIC) system is presented to automatically adjust the linearity performance of a tunable RF low-noise amplifier (LNA) operating at 2.4GHz. In this paper, we conduct research on optimization and ascension of target accuracy for RF systems. To minimize the area and power overhead of the system, an envelope detector was employed to reduce the speed of operation for the ADC and digital blocks, and an efficient IM3 estimation method has been developed. Closed-loop simulations of this calibration system and a low-noise amplifier with digitally-tunable third-order linearity performance showed the feasibility of the synthesized digital blocks in standard CMOS technology. The experimental result proves the effectiveness of proposed method.
