Analog Front-End Design Using The Gm/Id Method For A Pulse-Based Plasma Impedance Probe System, Arun J. Rao
Analog Front-End Design Using The Gm/Id Method For A Pulse-Based Plasma Impedance Probe System, Arun J. Rao
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Plasma Impedance Probe (PIP) is an electronic instrument that measures the impedance of a dipole antenna immersed in a plasma environment. Measurements made by the PIP provide valuable information regarding the plasma environment. Knowledge of ionospheric plasma density and density disturbances is required to understand radio frequency communication with satellites. The impedance curve provides us with significant plasma characteristics such as the electron-neutral collision frequency and plasma electron density.
The work proposed here is a transistor-level implementation of the analog front-end, the non-inverting amplifier that is used to drive the antenna. The antenna immersed in plasma is excited with …
