Abstract :
The noise figure of a transistor converter may be expressed in terms of the usual transistor and circuit parameters (source resistance, base resistance, emitter-base diode impedance, current gain, cutoff frequency, and conversion conductance). Theoretical values are in good agreement with measured values.
