Abstract
A switch impedance insensitive signal processor is provided. A signal processor according to the present invention overcomes the problem of switch impedance by adding an individual buffer, e.g. a unity-gain amplifier, between the switch and the processor portion of the circuit. The buffer isolates the signal processor from the switch impedance.
