[ 1 ] - Modeling of Substrate Noise Impact on a Single-Ended Cascode LNA in a Lightly Doped Substrate (RESEARCH NOTE)

Substrate noise generated by digital circuits on mixed-signal ICs can disturb the sensitiveanalog/RF circuits, such as Low Noise Amplifier (LNA), sharing the same substrate. This paperinvestigates the adverse impact of the substrate noise on a high frequency cascode LNA laid out on alightly doped substrate. By studying the major noise coupling mechanisms, a new and efficientmodeling method is p...
