Abstract:
A receiver comprising:a first impedance having a first terminal for connection to a voltage source providing an input voltage with respect to a ground reference and a second terminal connected to a first junction node; a second impedance having a first terminal connected to the first junction node and a second terminal connected to a second junction node; a third impedance having a first terminal connected to the second junction node and a second terminal connected to the ground reference; a fourth impedance having a first terminal connected to the first junction node and a second terminal connected to a third junction node; a first amplifier having a non-inverting input connected to the second junction node, an inverting input connected to the third junction node and an output connected to an output node providing an output voltage with respect to the ground reference; and a variable gain second amplifier having an input connected to the output of the first amplifier, an output connected to the third junction node, an automatic gain control input and a gain of; 1K;wherein the value of K is a real number greater than zero and set by the automatic gain control input.
