HIGH PERFORMANCE CURRENT SOURCE POWER SUPPLY

摘要

A system can include a device under test (DUT) having a DUT voltage, a cable connected to the DUT, the cable having a cable inductance, and a power supply configured as a current source to provide a wide bandwidth voltage source to the DUT, wherein the DUT voltage is independent of the cable inductance.

1. A system for sourcing a voltage, comprising:
a remote capacitor; a voltage-control-current-source having a deterministic transconduction; a first cable connecting an output of the voltage-controlled-current-source to the remote capacitor; a second cable connecting an input of the voltage-controlled-current-source to the remote capacitor, wherein the remote capacitor is of a size such that it dominates the open loop gain frequency roll-off though a gain of one.
