Silicon photonic devices can be built using commercial CMOS chip fabrication facilities, or 'fabs'. However, nearly all research groups continue to design, build and test chips internally ...

The Columbia Engineering team collaborated with Alyosha Christopher Molnar, Ilda and Charles Lee Professor of Engineering at ...

Welcome to part one of a series taking you down the rabbit hole of DIY electronic synthesizers based on (largely) CMOS logic chips. Instead of synths being commodity gear made by large corporate ...

Columbia engineers have created a powerful 3D photonic-electronic chip that could overcome one of AI’s biggest hardware ...

Let’s clarify a few things first. A CMOS chip is vastly different than the CMOS battery on your motherboard. CMOS is a MOSFET-type technology used for logical operations. In simple terms ...

Artificial intelligence (AI) systems promise transformative advancements, yet their growth has been limited by energy ...

As with Bluetooth, there is a desire to reduce the chip count by integrating the entire stack, including the RF as a part of a larger ASIC or SoC. One key reason why 90nm CMOS is of interest in this ...

A CMOS-based chip that records the intensities of light as variable charges similar to a CCD chip. Although initially used in less expensive digital cameras, the quality of CMOS sensors has ...

This work proposes a technological platform able to deliver CMOS-compatible, on-chip multi-frequency, low-loss, wide-band, and compact filters for cellular radios operating in this range by leveraging ...
