By Anil Pandey, EDAboard.com member The switching is required in many applications at low as well as at high frequency. RF MEMS switches are the specific micromechanical switches that are designed to operate at RF to mmWave frequencies. MEMS switches usages some mechanical movement to achieve a closed or open circuit in the Radio Frequency […]
Analog IC Tips
PCIe Gen 4-compliant clock buffers powered from single 1.5 V/1.8 V supplies
Silicon Labs has introduced a new family of low-power PCI Express (PCIe) Gen 1/2/3/4 clock buffers that provide ultra-low jitter clock distribution in 1.5 V and 1.8 V applications. With additive jitter performance of 40 fs RMS (typical), Silicon Labs’ new Si532xx PCIe clock buffers provide more than 90 percent margin to stringent PCIe Gen 3 […]
Quick-connect attenuators span frequencies to 6 GHz
Fairview Microwave Inc., a supplier of on-demand RF and microwave components, has introduced a new line of attenuators for quick mating and easy installation. Typical applications include remote radio heads (RRHs), DAS systems, base stations and antennas. Fairview’s new line of quick connect attenuators is made up of 31 models that support operating frequency ranges from DC […]
Rotary encoders, Part 2: magnetic encoders
Part 1 of this FAQ looked at the optical rotary encoder, a low-cost, high-resolution, easy-to-use sensor for indicating incremental shaft position (although it can be “upgraded” to indicate absolute position as well). Q: What is the basic principle of the magnetic encoder? A: The magnetic encoder uses a rotating gear made of ferrous metal and […]

Top analog IC stories of 2017
Here are the analog IC features that got the most interest from readers in 2017. The voltage follower or unity gain amplifier in a voltage divider Operational amplifiers have a very high input impedance, which means that they don’t suck in much current (ideally, none) at the inputs. Op amps also […]
Common emitter circuit for analog signal amplification
Today’s microcontrollers are crammed with useful features that have obviated the need for going off chip in order to gain useful functionality. So-called “system-on-chip” or SoC platforms have streamlined product development cycles. They have done this by allowing engineers to spend more time focusing on value-added work and less time on the more mundane glitches […]
Demystifying SPICE noise simulation
While I have covered the basics of noise simulation in SPICE before, I thought it was worth revisiting the subject to show some of the confusing results you can sometimes get and how to interpret them. The example I used earlier, a simple opamp based amplifier, didn’t show any unusual noise results but other circuits […]

Op amp ICs feature superior EMI immunity in all bands
Automotive-grade ground sense opamps ar esaid to deliver breakthrough EMI tolerance (noise immunity) for automotive systems using sensors. Developed using proprietary layout, processes, circuit design technologies, the BA8290xYxx-C series features superior noise immunity that suppresses output voltage fluctuation in all frequency bands to less than ±1%, compared to ±3.5% to ±10% with conventional products. The […]
