AMPLIFIER ARRANGEMENT WITH PARALLEL-OPERATED AMPLIFIER SECTIONS

摘要

PHN 9596 6 An amplifier arrangement having an input coupled to the input of n amplifier sections (n ? 2), whose outputs axe connected single-ended, each via a corresponding resistor, to a common output circuit. The voltage derived from the output of the kth amplifier section is applied together with the input voltage of this amplifier section to a difference element whose output signal is applied to the input of the (k+1)th amplifier section (k ranging from 1 to n and n+1 representing the first amplifier section). By means of this measure an arrangement has been obtained which has a very low distortion and also has a very high output power.
