Fluidic die sense architecture

A fluidic ejection system comprising:

• a controller to provide a set of addresses and a set of sense enable signals, each sense enable signal having an enable value or a disable value;
• a fluidic die including:
• a sense architecture including:
• a global sense block to provide an analog reference signal;
• and
• an array of distributed sense blocks, each distributed sense block corresponding to a different enable signal of the set of enable signals, each distributed sense block including:
• an array of sensors, each sensor corresponding to a different address of the set of addresses;
• and
• a sense circuit to:
• apply the analog reference signal to the sensor corresponding to the address on the address bus when the corresponding sense enable signal has the enable value;
• and
• provide to the global sense block an analog sense signal from the sensor resulting from application of the analog reference signal.

A method operating a fluidic die having a plurality of sensors comprising:

• arranging the plurality of sensors into a number of sensor arrays with each sensor having a same set of addresses and having a corresponding enable signal, with each sensor of each sensor array corresponding to a different address of the set of addresses;
• providing a global analog reference signal;
• providing addresses of the set of addresses on an address bus;
• providing a set of enable signals, each enable signal corresponding to a different one of the sensor arrays and having an enable value or a disable value;
• and
• applying the global analog reference signal to the sensor corresponding to the address on the address bus of the array of sensors having a corresponding enable signal with an enable value to generate an analog sense signal.
