Application Note Stabilizing Fast Transient Response
Series Power Supply/Load Circuits
Introduction wires and a pair of load voltage sensing wires. The wires in each
pair are twisted together to minimize spurious voltages result-
Keithley's Series 2300 Battery/Charger Simulators (fast transient
ing from induced magnetic fields. The test fixtures often employ
response power supplies) are specifically designed for powering
bypass capacitors to minimize AC noise. To understand how the
RFIC power amplifiers, mobile phone handsets, and other por-
load circuit performs for analysis of short load current pulses
table, battery-operated products in R&D and manufacturing envi-
(effectively an AC signal), the two pair of wires must be modeled
ronments. These battery-simulating power supplies are designed
as an AC network of distributed resistive, series inductive, and
to recover very quickly from short-duration pulse load current
parallel capacitive components. The test fixture and DUT must
