Abstract
Voltage Enhancement Circuitry (VEC) for amplifiers, suitable of being implemented as an Integrated Circuit (IC), that comprises a VEC driver with a low output resistance (Rdson) while being in its inactive mode and a linearly increasing resistance that is changing linearly with the input control signal, while entering into its active mode, above a determined threshold; external contacts in the VEC, for connecting, whenever required, external feedback elements across the contacts; an external feedback loop connected to an input of the VEC driver, for sensing changes in the enhancement power; a threshold programming module, for externally programming and determining a threshold level for the input signal, above which enhancement is provided shaping the amplified video envelope pulse; an I-Boost module for sampling the amplitude of the video envelope input current and for amplifying the input current up to a pre-defined level; and a current controlled bias circuit for shifting, whenever required, the bias of the lower and/or of the upper valves of the VEC driver.
