Abstract:
1. A multiple input single output (MISO) amplifier, comprising: a plurality of inputs that receive a plurality of input signals; a plurality of circuit branches coupled to said plurality of inputs, said circuit branches each comprising one or more transistors; and an output; wherein said input signals are amplified and combined to create an output signal at said output of said MISO amplifier; wherein a first output voltage of a first transistor in a first circuit branch tracks a second output voltage of a second transistor in a second circuit branch, wherein said tracking occurs regardless of input bias voltage applied to inputs of said first and second transistor; wherein said first and second output voltages of said first and second transistors, respectively, form a singular output voltage at said output of said MISO amplifier.
