An Improvement of Out-of-Band Suppression in Common-Gate LNA with Transformer-Based Input Matching Network for BLE Applications
Abstract: The purpose of this paper is to improve out-of-band suppression in capacitive cross-coupling common-mode LNA with transformer-based input matching for BLE applications. Starting from an overview of the transformer-based matching network, the problematic issue is addressed through analytical considerations and its solution is presented. Transformer-based matching introduces an undesired peak response by an extra conjugate pole pair owing to the imperfect magnetic coupling of the transformer which degrades the suppression …
