Proceedings Ninth Annual IEEE International ASIC Conference and Exhibit.
Compact and fast photoreceivers with on-chip photodiodes in standard CMOS technology have been developed as optical inputs for digital circuits. The time performance of different photodiodes and current/voltage converters has been investigated and op

1997 IEEE International Conference on Microelectronic Test Structures Proceedings.
Conventional needle probe techniques do not permit wafer level tests at frequencies above about 100 MHz. As an alternative to special probes like microwave strip lines optical inputs have been designed which have been shown to operate up to 800 MHz i

International Symposium for Testing and Failure Analysis.
Conventional needle probecard techniques suffer from several problems: needles scratch the pads causing bonding problems, the maximum test speed is limited by the poor high frequency performance of the needle contacts. This contribution presents a ne
