Abstract:
1. An integrated circuit comprising: A. a substrate of semiconductor material; B. analog circuitry formed on the substrate, the analog circuitry having an analog stimulus input, an analog response output, a positive voltage input, and a negative voltage input; and C. test circuitry formed on the substrate, the test circuitry having an analog test input electrically isolated from the analog response output and adapted to be selectively connected with the analog response output, an analog reference input electrically isolated from the analog circuitry, a strobe input electrically isolated from the analog circuitry, an analog test response output electrically isolated from the analog circuitry, a test positive voltage input electrically isolated from the analog circuitry and adapted to be selectively connected with the positive voltage input of the analog circuitry, and a test negative voltage input electrically isolated from the analog circuitry and adapted to be selectively connected with the negative voltage input of the analog circuitry.
