---++++ 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.
