This article details the common problems plaguing analog voltage mode control loops and shows how a digital control loop is able to provide bandwidth that was previously dismissed as unobtainable. By walking through the variables associated with stability and comparing it to an analog control system, it can be seen that...

Automating Sub-mmWave Front-End Module, Transceiver, and Modem Test.
As development schedules shrink under time-to-market pressures and product complexity increases with every iteration of communications and cellular standards, test groups need a test solution that they can scale and adapt while keeping costs in check....

Even though the eGaN FET was designed and optimized as a power-switching device, it also exhibits good RF characteristics. The smallest 200 V eGaN FET, EPC2012, was selected for RF evaluation and should be viewed as a starting point from which the RF characteristics of future eGaN FET part numbers can be optimized for...

We are witnessing one of the greatest revolutions in all of human history – a revolution driven by artificial intelligence and the Internet of Things.
AI has long been seen as ‘something of the future’, but it is now impacting our daily lives. This is happening within many areas,...

Changes in power supply design are rarely revolutionary. Rather, they are evolutionary and dependent upon a host of component and manufacturing technologies that, for the most part, develop at a modest pace. Moore’s law simply doesn’t apply to power supply design; if it did, a 200 W switcher the size of a thumbnail...

Type-C interfaces bring dramatic benefits to consumers. However, in order to realize this potential designers must implement Type-C's Power Delivery (PD) protocol, detect cable orientation and switch high speed signals, as needed and, if desired, provide support for Vendor Defined Messaging (VDM).
This whitepaper...

The intention of this paper is to analyze the overhead of memory used, while employing a C compiler as opposed to Assembly for PICmicro® MCU projects. The example code and the numbers used in this paper are for a 14-bit opcode target processor. ROM location counts are given for 14-bit words. For estimation purposes,...

In addition to voice connectivity, digital cellular wireless networks such as GSM and its enhancement, GSM-EDGE, can now provide increased data speeds up to a (theoretical) limit of 384Kbps. Third generation mobile networks, such as CDMA2000 and WCDMA or UMTS (Universal Mobile Telecommunications Standards) and TDSCDMA...
