1. A control circuit to receive a control signal from a surgical generator, the control signal defining a first phase and a second phase, the control circuit comprising:
a resistor network comprising resistors arranged in parallel to each other;
a capacitor coupled in series with the resistor network; and
a plurality of switches, each of the switches configured to transition between an open state and a closed state;
wherein the control circuit is to transition between a plurality of states corresponding to a plurality of operational modes of a surgical instrument;
wherein, in the first phase of the control signal, the control circuit is to communicate surgical instrument information to the surgical generator;
wherein, in the second phase of the control signal, the control circuit is to provide an output corresponding to one of the plurality of states of the control circuit;
wherein the plurality of switches are configured to transition the control circuit between the plurality of states; and
wherein a state of the plurality of switches is determinable based on a slope of a voltage of the capacitor.
