Introduction to OCXO   The oven-controlled crystal oscillators (OCXOs) are a promising technology to minimize the impact of temperature on crystal oscillators by controlling the surrounding temperature. The OCXOs produce stable frequency by controlling and regulating the temperature of the crystal element. This establishment is becoming a valuable solution for precise timing applications. This paper presents a general guideline for OCXO technology.   Definition and Overview of OCXOs   Oven controlled crystal oscillators (OCXOs) are a highly précised clock type of crystal oscilla ..read more

Introduction   Temperature-compensated crystal oscillators (TCXOs) are enhanced crystal-type oscillators that integrate temperature compensation techniques to minimize frequency instability by temperature variations. It is a good choice for precise and stable clock signals than traditional standard oscillators. TCXOs are preferred since temperature variations can be addressed by adding temperature-compensated circuits, which helps the crystal to have a consistence temperature even when fluctuations appear in the surroundings. This article is composed of a general review of TCXO’s importan ..read more

Introduction   The drive for size miniaturization in wireless electronics devices led to antennas being reduced in size and deployed in an ultra-compact way, which is referred to as chip antenna technology. New antenna designers are always coming up with novel techniques to minimize size, save costs, and enhance the performance and efficiency of the antenna. The compactness of chip antennas makes them an appealing alternative for smaller integrated applications.   Definition of Chip Antenna   Chip antennas are very small, ultra-compact, and low profile antennas that are fabrica ..read more

Introduction to PCB Antennas   In the communication industry, an antenna is a critical component, to allow transmit or receive electromagnetic waves. In the early age of antenna technology, the antenna was typically large, mounted on the external structure of the transmitter or receiver. The idea of a PCB antenna appeared in the early 1970s when antenna researchers started to investigate the use of a printed circuit board (PCB) instead of a separate antenna substrate. They intended to integrate antenna parts directly on the PCB, eliminating the need for separate substrates. Currently, the ..read more

We had a pleasure talking with, Michael Worry, CEO of Nuvation Engineering. Here is our full interview:     Tell me a bit about your background? How did you first get started with Nuvation Engineering?   I founded Nuvation Engineering in 1997. I had recently graduated from the University of Waterloo’s Engineering program and after working for a few companies, I decided to start my own. I moved from Waterloo to Silicon Valley in California and started Nuvation as an engineering design services company.   Tell me about Nuvation Engineering ?   Nuvation started as a ..read more

  HQ NextPCB is proud to announce the release of HQDFM Online Gerber Viewer and DFM Analysis Tool, free for everyone. With HQDFM, NextPCB hopes to empower designers with the DFM tools and knowledge to perfect their designs as early as possible, where problems are the least costly.   The PCB manufacturing industry has and still relies on the Ucamco Gerber standard to communicate PCB production to manufacturers, which are often located overseas. While the 2D image format overcomes language barriers, the language of PCB Design for Manufacture is still ambiguous to many inexperienced de ..read more

STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has introduced a new generation of energy-conscious and cost-effective microcontrollers (MCUs) that can reduce energy consumption by up to 50% compared to previous product generations. This enables less frequent battery replacements, minimizes the impact of discarded batteries, and allows more designs to go battery freerunning solely from an energy-harvesting system such as a small photovoltaic cell.   In the global pursuit of sustainability, technologies deploy ..read more
