RF switches, Part 2: Analog and MEMS switches
Part 1 of this FAQ looked at the venerable electromechanical RF switch – still widely used in some applications, where it is the only viable option—and the use of PIN diodes as RF switches. This part looks at analog and MEMS-based switches. Q: What is an analog switch? A: It’s conceptually straightforward: in basic form, […]
RF switches, Part 1: Mechanical and PIN-diode switches
There’s a ubiquitous and increasing need to switch RF signals ranging into the tens of GHz; four basic switch technologies – electromechanical, PIN diode, analog, and MEMS – are available, each with different features and capabilities. The need to switch RF signals has been a necessary design function since the earliest days of “wireless.” This […]
Impedance/P\potentiostat Analog Front End handles biological, chemical sensing
Analog Devices, Inc. announced a new electrochemical and impedance measurement front end that enables the next generation of vital sign monitoring devices and intelligent electrochemical sensors. The AD5940 analog front end incorporates both potentiostat and electrochemical impedance spectroscopy (EIS) functionality on a single chip, allowing for sensor measurement in both time and frequency domains. The […]

Analog computation, Part 2: When and how
Analog circuits based on op amps can be used to implement mathematical functions and are still useful in many applications due to their unique attributes. Part 1 of this FAQ looked at the basic need for and virtues of analog-based computational circuits. Part 2 looks at some implementation specifics and considerations. Q: What are the […]
Analog computation, Part 1: What and why
Analog circuits based on op amps can be used to implement mathematical functions and are still useful in many applications due to their unique attributes. Say the word “computer” or “computation” and the instinctively associated concept is “digital.” That makes sense since most computers and computation functions are implemented with general digital logic, specialized arithmetic […]
Synthesized tuning, Part 2: Advanced synthesizers and performance
Part 1 of this FAQ looked at the basic issues and topologies related to the challenge of frequency synthesis. Part 2 continues with advanced approaches and their attributes, as well as general concerns when choosing a synthesizer. Q: Are there other digitally-controlled synthesizer topologies? A: Yes. A widely used one is called the classical phase […]
Synthesized tuning, Part 1: Basic frequency-synthesizer principles
Frequency synthesizers of various architectures, made possible by IC technology, are a key building blocks for applications which must accurately tune multiple channels, and hop from one frequency to another while using a single signal source such as a crystal oscillator. When you want to tune a desired radio station — AM or FM — […]
Wheatstone bridge, Part 2: Additional considerations
Part 1 of this FAQ explained the basic principle of the Wheatstone bridge. This part will take the bridge configuration into modern applications and go beyond basic resistance measurements. Q: All this measurement via changing resistance or by measuring current seems very slow or static; how does it fit into today’s electronics? A: First, many […]
