if there are two single inputs to a difference amplifier are Va and Vb. And these inputs are simple function of cos or sin with different frequency and phase. then the difference of these is very simple by Vo=Vb-Va.
However, what if the two inputs of the diff amplifier are infact the outputs of two different mixers (each mixer output has sum and difference components). Can a single amplifier on its own gives single output based on the given inputs? OR multiple difference amplifier is needed to integrate?
Also please state that in terms of size, whether the size on chip will be greater?
Any alternative to this type of operation if someone can provide, please state. Thanks
