Abstract
A complementary balanced low-noise amplifier is disclosed. In one aspect, the low-noise amplifier (LNA) may be a single-ended cascoded complementary common-source LNA that is capable of operating in low-power conditions. In particular, the LNA may include a first path with a common-source amplifier formed from an N-type material and a second path with a common-source amplifier formed from a P-type material that collectively form a complementary common-source amplifier. By providing two paths in the complementary amplifier, headroom may be preserved for output transistors. Additionally, higher-order intercept points (e.g., IP2 or IP3) characteristics have better performance profiles resulting in better overall performance and improved user experience.
