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.
This chip implements a 1:4 single-ended binary-tree demultiplexer designed for ultra-high-speed serial data systems. It converts a high-rate serial input stream into four parallel outputs, enabling subsequent digital circuits to operate at lower clock frequencies.
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.
Reference-Less CDR with Autonomous Acquisition
A reference-less 28 Gbps Non-Return-to-Zero (NRZ) full-rate Bang-Bang Clock and Data Recovery (BBCDR) circuit is demonstrated for high-speed optical transceivers. Implemented in IHP’s 250 nm SiGe BiCMOS (SG25H4) technology, the design is compatible with Electronic–Photonic Integrated Circuit (EPIC) integration.
