Abstract :
An 8-channel mixed-signal tester integrated circuit that is suitable for very low footprint test applications is described. It is capable of simultaneously stimulating eight analog or mixed-mode devices under test and coherently digitizing eight device responses at an amplitude resolution of 12-b and a bandwidth of 20-MHz. The circuit is fabricated in a 2.5 V, 0.25 /spl mu/m CMOS process, and achieves a SFDR of over 70 dB at 20 MHz with a maximum DNL of 0.15 LSB. It owes its compactness to a versatile, mostly digital architecture that is easily synthesizable. Software-based performance evaluation and calibration is also described.
