“…In a scheme with n modules connected in series, the current through the cable is reduced by a factor n with respect to the parallel powering of n modules whereas the voltage drop across the module chain corresponds to n times the voltage drop across a single module. Neglecting the inefficiency caused by the regulation circuitry, the improvement in powering efficiency can be calculated to be [5]: 1+1 +~w here n is the amount of powered modules, R is the cable resistance, I is the current drawn and V is the voltage across a module.…”

In this paper, a new type of regulator is proposed for integration in ASICs used in serially powered systems. In the serial powering scheme, modules are placed in series and fed by a constant current source to reduce the IR drop on the cables which increases powering efficiency. At the module level the needed supply voltages are generated redundantly out of the current supply by several parallel operating ASICs with integrated regulation circuitry. A Shunt-LDO regulator has been developed to allow robust and redundant regulator operation and the generation of different supply voltages by parallel placed devices. The Shunt-LDO regulator scheme combines the capability of Low Drop-Out regulators to generate a constant supply voltage with the feature of shunt regulators to assure a constant current flow through the device. The Shunt-LDO regulator has been developed for application in the framework of next generation hybrid pixel detectors used in high energy physics experiments. This circuit has been prototyped in a 130nm CMOS technology, capable of generating voltages in a range of 1.2-1.5V with a minimum drop out voltage of 200m~The maximum shunt current is 500mA with a load regulation factor corresponding to an output impedance of 30mn.

“…First implemented at the Univ. Bonn [35,36], this arrangement has also been tested at RAL [37] and LBNL [38], demonstrating full operation with little or no increase in noise. A stave design that integrates the detector module and support structure with the module services also contributes to material reduction [38].…”

The past quarter century has brought about a revolution in front-end electronics for largescale detector systems. Custom integrated circuits specifically tailored to the requirements of large detector systems have provided unprecedented performance and enabled systems that once were deemed impossible. The evolution of integrated circuit readouts in strip detectors is summarized, the present status described, and challenges posed by the sLHC and ILC are discussed. Performance requirements increase, but key considerations remain as in the past: power dissipation, material, and services. Smaller CMOS feature sizes will not provide the required electronic noise at lower power, but will improve digital power efficiency. Significant improvements appear to be practical in more efficient power distribution. Enhanced digital electronics have provided powerful trigger processors that greatly improve the trigger efficiency. In data readout systems they also improve data throughput, while reducing power requirements. Concurrently with new developments in high energy physics, detector systems for cosmology and astrophysics have made great strides. As an example, a large-scale readout for superconducting bolometer arrays is described.

Serial powering is a technique to provide power to a number of serially chained detector modules. It is an alternative option to independent powering that is particularly attractive when the number of modules is high, as in largescale silicon tracking detectors for particle physics. It uses a single power cable and a constant current source. On each module power is derived using local shunt regulators. Design aspects of local shunt regulators and system aspects of serial powering will be discussed. Test results and measurements obtained with a silicon strip supermodule will be presented. Specifications of radiation-hard custom serial powering circuitry will be discussed.
