---++++ Shunts

The current drawn by the readout ASICs depends on their operational mode. The constant current<br />supply is set to the maximum expected hybrid current and shunt regulation is used to keep the<br />voltage across the hybrid constant. The latest generation of prototype readout ASIC is made in the<br />IBM 250nm process and termed ABCN-25 Already, this ASIC contains custom circuitry for<br />the implementation of shunt regulation.

There are two shunt regulation options within the ABCN-25, termed M-shunt and W-shunt.

The M-shunt option uses two shunt transistors in each ASIC, controlled by a voltage from an<br />external circuit.

The W-shunt option uses both shunt and control circuitry within the ASIC itself.

Shunt regulation may also be implemented outside the readout ASIC, using discrete compo-<br />nents or an additional ASIC.

---++++ Addressing of ASICS and Hybirds

On each hybrid panel each ASIC can be addressed by a combination of wire bonds to the PCB., It's different for each asic on the hybrid, but this system does not change from hybrid to hybrid <br /> <br />This allows one row of asics to be numbered 32-41 and the other 64-73 <br /> <br />When the module is being wire bonded, each hybrid panel is wire bonded to another mounted pcb on the module (the BCC) <br /> <br />The left one (if the HV lines are at the top) is wire bonded to label it BCC=61, and the right BCC=62 <br /> <br />This systems stays the same for every module we wire bond. <br />. <br /> <br />At the system tests point I address each Hybrid by it's BCC number, and it has it's own associated data file <br /> <br />If i name 4 hybrid files differently, you can then test 4 hybrids (2 modules) even if there are 2 panels with a BCC of 61, and 2 with a BCC of 62
