Patent ID: 7701242

Claim:
An electronic circuit to determine current-voltage characteristics of a plurality of electronic devices under test, the electronic circuit comprising: a plurality of individual test cells, each of the plurality of individual test cells configured to electrically couple to a first terminal of one of each of the plurality of electronic devices under test, each of the plurality of test cells including: a pair of switching devices coupled in series with one another and configured to receive an enable signal on a gate of each of the switching devices, a junction of the pair of switching devices configured to be coupled to the first terminal of the one of the plurality of devices under test; and a transconducting device having a gate coupled to a first end of the pair of switching devices; and a first current source coupled to a second end of the pair of switching devices in each of the plurality of individual test cells; and a second current source configured to be coupled to a second terminal of each of the plurality of electronic devices under test.
