The future of IC design

To celebrate 60 years of EDN, we’re looking into the future to predict what advancements will be made in IC Design in the next 60 years. By 2076 3-D room-temperature, superconducting, quantum, neuromorphic, and photonic mixed-signal devices will be the common denominator for all integrated circuit designs. Design tools will be so sophisticated that even novice designers will be able to mix and match these t ...

555 timer teardown: inside the world’s most popular IC

If you've played around with electronic circuits, you probably know[1] the 555 timer integrated circuit, said to be the world's best-selling integrated circuit with billions sold. Designed by analog IC wizard Hans Camenzind[2] in 1970, the 555 has been called one of the greatest chips of all time with whole books devoted to 555 timer circuits. Given the popularity of the 555 timer, I thought it would be int ...

Monolithic terabyte memory IC

Crossbar, the RRAM specialist, says it has solved a major obstacle to RRAM’s commercialisation – what Crossbar calls ‘sneak path current’ which is akin to leakage in CMOS circuits but particularly destructive in RRAMS. This, breakthrough, says a Crossbar press release: “Signals Crossbar’s 3D RRAM readiness for commercialisation of Terabyte storage-on-a-chip.” So how far away from production is an 8Tbit memo ...

Precision programmable current source uses two ICs

This Design Idea mates a precision current source IC with precision difference amp chips to create a programmable current source or sink. The resistor-programmable current source/sink in Figure 1 illustrates the basic topology, taking advantage of tightly matched on-chip resistor ratios instead of relying on absolute tolerances. he IIN current source gives rise to a reference voltage across Rf at the op-amp ...

LED-based time-of-flight IC for object detection and distance measurement

Although Intersil's ISL29501 time-of-flight (ToF) signal processing IC doesn't have anything to do with the lighting applications I normally cover, I felt compelled to bring it to your attention because it's one of the most innovative LED applications I've seen this year. The device requires little more than an external emitter (LED or laser) and a photodiode to implement a complete object detection and dis ...
