Most high-frequency signals are unable to penetrate the Earth's surface and lower frequencies have a much higher chance of penetrating the surface. Ultra-low frequencies can be used to penetrate the Earth's crust, but the frequency and background noise are a large problem that prevents from detecting these low frequency signals. This thesis describes the design for a small and lightweight low-frequency amplifier that can receive low voltage signals and amplify them to a level that could be used to do further analysis. The proposed amplifier design was capable of handling inputs as low as 1 muV and amplifying them to a level of 1mV. This thesis also describes how the amplifier can be tested along with the rest of a low-frequency detection system.
