Number 2870 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 changes as large as 1000% (i.e., a 10
