Abstract
A system for testing a microelectronic circuit includes a test bed for mounting a microelectronic circuit, and a signal source for applying a signal to a microelectronic circuit mounted on the test bed. The system additionally includes a test probe for wirelessly receiving electromagnetic response signals from the microelectronic circuit mounted on the test bed. In a preferred form, the electromagnetic response signals are radio-frequency signals. The test system additionally includes a computer connected to be test probe for analyzing the electromagnetic response signals. An integrated circuit for testing on the test system has a test circuit portion that emits electromagnetic radiation in response to a predetermined signal applied to the test circuit.
