  • Abstract
    This paper describes a low-noise two-transistor pre-amplifier which has been developed for use with microphones. For a source resistance of 1000 Ω, a noise figure of 1.3 db has been achieved. A corresponding middle-frequency gain of 40 db, bandwidth of 30 kc and output impedance of 175 Ω resulted.
