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.
Optical Arbitrary Waveform Measurement (OAWM) Using Silicon Photonic Slicing Filter
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.
