AN ANALYSIS OF THE BRETT ULTRA-WIDEBAND VIDEO AMPLIFIER
Abstract
A detailed analysis is made of the process of phase modulation by a nonlinear reactance element. This analysis is applied to a video amplifier circuit which shows this circuit to be capable of ultra-wideband amplification. The basic mechanism for this amplification is discussed in terms of several analytical viewpoints, which are ultimately shown to be consistent. Formulas for all basic circuit quantities are derived, including gain, bandwidth, input and output impedance, and noise figure. This analysis is used to predict optimum design techniques when nonideal components are incorporated in the circuit. An illustrative design is given for a video amplifier with 20 db gain, 100 Mc bandwidth (0 to 100 Mc), and a noise figure of less than 0.1 db. (Author)
