Analytical expression of the efficiency of phantom zero compensation applied on negative-feedback amplifiers
(2004) 22nd Norchip Conference, 2004 p.87-90- Abstract
- This article reviews the phantom zero compensation technique, applied on negative-feedback (NFB) amplifiers, followed by an analysis of the important efficiency parameter, 0, of the implemented phantom zero. The effect of the efficiency on the root locus is presented, and it has been found that δ 7 will give near ideal behavior of the applied phantom zero. A reduced small signal model of the amplifier is presented along with a modified feedback factor, β<sub>ph</sub>, which yields a simple analytical expression of the efficiency. The theory is independent of technology (BJT, FET, etc.), and exemplified on a two-stage BJT NFB amplifier. ©2004 IEEE.
