1. A circuit for dynamically processing a signal, the circuit comprising:
an input stage;
a first processing stage coupled to the input stage and a first output, wherein in a first operating state of the circuit, the first processing stage is configured to process and output a first signal, wherein in a second operating state of the circuit, the first processing stage is configured to output a high impedance, and wherein the first processing stage is configured to switch between the first operating state and the second operating state based on a first control signal and a second control signal; and
a second processing stage coupled to the input stage and a second output that is distinct from the first output, wherein in the first operating state of the circuit, the second processing stage is configured to output a high impedance, wherein in the second operating state of the circuit, the second processing stage is configured to process and output a second signal, and wherein the second processing stage is configured to switch between the first operating state and the second operating state based on the first control signal and the second control signal.
