Abstract:
A distributed power supply delivery network includes an analog biased circuit array having current sources for delivering current to adjacent circuits, and a resistive ladder of resistor elements, where each resistor element is disposed between adjacent current sources. A tuned IR voltage drop network is included to match voltage drops across the resistive ladder. The tuned IR voltage drop network includes series connected resistors and a static current draw to induce the IR drop. The resistors may be matched with respect to the distributed power supply delivery system. The current source providing the static current for the IR drop may be programmed based on the power supply delivery load, in order to adjust the voltage drop across the biasing delivery route and match the voltage drop in the referenced power supply.
