Abstract
Apparatus for interconnecting two or more high gain, low input impedance amplifier stages for high gain amplification. A first amplifier stage (12) provides a first amplified signal to a coupling circuit. The coupling circuit (26) divides the power of the first amplified signal between the input to a second amplifier stage (14) and a feed forward path (28). The output of the second amplifier stage is combined with the feed forward portion of the first amplified signal in a signal combiner (30). Embodiments (FIGS. 4, 5) employing more than two amplifier stages are described.
