An ultra-low-noise preamplifier front end configuration is determined through the analysis of the noise behaviour of a bipolar transistor, current mirror and an FET in relation to the noise performance of various preamplifier configurations. A design for Hi-Fi performance, in accordance with the demand for a low-noise, high-linearity and high-speed preamplifier for use with a magnetic transducer, is then presented.
