From French company IkaLogic, the IkaScope is a pen-shaped battery-powered wireless oscilloscope that streams captured signals to almost any Wi-Fi-connected screen. The IkaScope has 30 MHz bandwidth with 200 Msample/sec sampling rate and the maximum input is ±40 Vpp...
Single switch serves dual duty in small, microprocessor-based system
Traditional control-system designs use separate switches to control power and various system functions, but adding a few components to a small, microprocessor-based system can combine a control function with the system's on/off switch. For example, you can design a system to display relative humidity and temperature...
Analog Devices' Wideband RF Power and Return Loss Measurement System Offers a Smaller Form Factor and Faster Time to Market
18.10.2017 · News
Analog Devices introduced a 9 kHz - 7 GHz directional bridge and dual RMS RF power detector that can simultaneously measure forward and reverse RMS power levels in a signal path along with return loss. The new ADL5920 detector represents a change to conventional approaches by integrating a directional bridge-based coupler that results in an industry leading level of integration and bandwidth...
Switched-capacitor voltage multiplier achieves 95% efficiency
17.10.2017 · Circuits
A capacitor that you charge through a resistor operates at 50% efficiency; hence, many engineers avoid using switched-capacitor dc/dc converters. That efficiency figure holds true only for capacitors with no initial voltage, however...

Torex Semiconductor has launched a new series of 3.0 A synchronous rectification DC/DC stepdown converters (XC9274/XC9275) with our unique HiSAT-COT high-speed transient response control...
Turn negative regulator «upside-down» to create bipolar supply from single source
12.10.2017 · Circuits
Despite the ever-growing choices among single-supply “Rail-to-Rail” op-amps, it will always remain true that the only way to design an output stage active all the way down to zero volts is for the design to include a negative power supply. This fact of life can be an annoying complication in simple battery-powered applications for example...
