Abstract

An amplifier having programmable amplification includes a transistor circuit having a plurality of negative feedback resistors, a switch being associated to a negative feedback resistor such that the negative feedback resistors of the transistor circuit can be activated and deactivated selectively by operating switches via a controller. Thus, a broadband amplifier having a high linearity can be implemented.
