A 5.7mW Silicon Germanium Pre-Amplifier was constructed, characterized, and its potential impact on image quality demonstrated. The amplifier demonstrates significant power savings relative to current implementations at the cost of increased device non-linearity and decreased input impedance. A benchtop measurement setup was constructed to simulate coils signals in conjunction with a physical receive chain. Measured image distortion began at peak input powers of -25dBm. This corresponds to high bandwidth, high dynamic range imaging sequences. For small coil sizes this distortion may not play a role, reducing the power barrier to wireless receive arrays.
