Abstract:
An amplification module comprising:a first group of amplifiers, each amplifier of the first group having (i) an inverting input port coupled to a first module inverting input terminal and (ii) a non-inverting input port coupled to a first module non-inverting input terminal; wherein inverting output ports of each of the first group of amplifiers are coupled to a module inverting output terminal, and non-inverting output ports are coupled to a module non-inverting output terminal; a divider network including differential input ports and differential output ports; wherein the divider network inverting input port is coupled to the first module inverting input terminal and the divider network non-inverting input port is coupled to the first module non-inverting input terminal; wherein the divider network inverting output port is coupled to a second module inverting input terminal and the divider network non-inverting output port is coupled a second module non-inverting input terminal; and a second group of amplifiers, each amplifier of the second group (i) corresponding to one of the amplifiers in the first group, (ii) having an inverting input port coupled to the second module inverting input terminal, and (iii) having a non-inverting input port coupled to the second non-inverting input terminal; wherein inverting output ports of the second group of amplifiers are coupled to the inverting output terminal and non-inverting output ports of the second group of amplifiers are coupled to the non-inverting output terminal.
