Phase-Synchronizer based on gm-C All-Pass Filter Chain

open access: yesAdvances in Electrical and Computer Engineering, 2012
The use of analog CMOS circuits at high frequency has gained much attention in the last several years. At the heart of rapid prototyping of these circuits is the concept of using a versatile library of common RF function blocks. The blocks (cells) must

Silicon-based distributed voltage-controlled oscillators [PDF]

open access: yes, 2001
Distributed voltage-controlled oscillators (DVCOs) are presented as a new approach to the design of silicon VCOs at microwave frequencies. In this paper, the operation of distributed oscillators is analyzed and the general oscillation condition is ...

A 24-GHz SiGe Phased-Array Receiver—LO Phase-Shifting Approach [PDF]

open access: yes, 2005
A local-oscillator phase-shifting approach is introduced to implement a fully integrated 24-GHz phased-array receiver using an SiGe technology. Sixteen phases of the local oscillator are generated in one oscillator core, resulting in a raw beam-forming ...

A low power 2 x 28 Gb/s electroabsorption modulator driver array with on-chip duobinary encoding [PDF]

open access: yes, 2014
An integrated 2 x 28 Gb/s dual-channel duobinary driver IC is presented. Each channel has integrated coding blocks, transforming a non-return-to-zero input signal into a 3-level electrical duobinary signal to achieve an optical duobinary modulation.

A 130‐nm SiGe BiCMOS On‐Chip Diplexer With High‐Q Inductors for K/Ka‐Band Applications

open access: yesInternational Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
This paper presents a high‐performance on‐chip diplexer designed for K/Ka‐band applications, fabricated via 130‐nm SiGe BiCMOS across two distinct frequency bands: 17–21 and 27–31 GHz. A localized backside etching (LBE) technique is employed to create air cavities beneath the inductors, a method that fundamentally mitigates substrate‐related losses and

Demonstration of a Graphene Adjustable‐Barriers Phototransistor with Tunable Ultra‐High Responsivity

open access: yesAdvanced Optical Materials, Volume 13, Issue 18, June 26, 2025.
A novel graphene‐based phototransistor with a tunable ultra‐high responsivity of 1.7 x 107 AW−1 has been demonstrated. Due to the selected material combination of amorphous silicon, graphene and n‐germanium, the device is potentially capable of dual‐band detection in the VIS‐IR range.
