The displayed chip is a novel opto-electronic Track-and-Hold Amplifier (OE-THA). The OE-THA can be used as a sampler in a photonic analog-to-digital-converter (ADC). It is fabricated in a silicon photonic 250 nm SiGe BiCMOS technology to allow for monolithic integration of photonic and electronic components.
This chip represents the world's first optoelectronic millimeter-wave radar transmitter integrated circuit (IC) for multiple-input multiple-output (MIMO) imaging radar, developed using silicon photonics technology.
The presented chip is a monolithically integrated coherent receiver designed to support high symbol rates (up to 64 GBd) necessary for inter- and intra-datacenter fiber-optic links. It represents a significant technological advancement as the first monolithic, single polarization coherent ePIC receiver operating at 64 GBd.
70 GHz Large-signal Bandwidth Sampler Using Current-mode Integrate-and-Hold Circuit for AD
In modern digital communication systems and broadband measurement equipment, high speed broadband analog-to-digital converters (ADCs) are key components. Ultrabroadband ADCs use time-interleaved sampling which makes it possible to achieve very high sampling rates above 100 GS/s.
Scale4Edge ecosystem demonstrator chip for an industrial audio event detection application developed as part of the Scale4Edge project. The chip is manufactured in Globalfoundries’ 22FDX technology and contains a RISC-V CPU with custom Instruction-Set-Architecture Extensions (ISAX) for fast AI and DSP processing.
We demonstrate an optical arbitrary waveform measurement (OAWM) system that exploits a bank of silicon photonic (SiP) frequency-tunable coupled-resonator optical waveguide (CROW) filters for gapless spectral slicing of broadband optical signals.
