Shunts

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