High-Performance Analog And RF Circuit Simulation Using The Analog FastSPICE Platform At Columbia University
By Mentor, a Siemens Business - 08 Apr, 2015 - Comments: 0

The research group led by Professor Peter Kinget at the Columbia University Integrated Systems Laboratory (CISL) focuses on cutting edge analog and RF circuit design using digital nanoscale CMOS processes. Areas of research include design techniques for circuits operating below 1 V, digitally calibrated RF front ends for superior linearity performance, LO synthesizers for wireless applications,... » read more

Modeling High-Performance Analog And RF Circuits In Nanometer-Scale CMOS
By Mentor, a Siemens Business - 12 Mar, 2015 - Comments: 0

By Mick Tegethoff and David Lee Today’s consumer, communication, and computer electronic devices have clocks, communication interfaces, and high-speed signal-conditioning circuits that operate at radio frequencies (RF). Providing price-competitive products often requires monolithic integration of these circuits in low-power nanometer-scale bulk CMOS silicon. This is a worst-case scenario for... » read more

What Will Change In Design For 2015?
By Brian Bailey - 15 Jan, 2015 - Comments: 0

This year more than 26 people provided predictions for 2015. Most of these came from the EDA industry, so the results may be rather biased. However, ecosystems are coming closer together in many parts of the semiconductor food chain, meaning that the EDA companies often can see what is happening in dependent industries and in the system design houses. Thus their predictions may have already res... » read more

Manufacturing Bits: Dec. 23
By Mark LaPedus - 23 Dec, 2014 - Comments: 0

Higgs boson sensors At the recent 2014 IEEE International Electron Devices Meeting (IEDM) in San Francisco, CERN described the tiny hybrid pixel detectors used at the Large Hadron Collider (LHC). Using CMOS technology, hybrid pixel detectors identify and tag individual sub-atomic particles at fast speeds. CERN, the European Organization for Nuclear Research, is a particle physics laboratory... » read more

How To Test IoT Devices
By Mark LaPedus - 11 Dec, 2014 - Comments: 0

At a recent event, test experts said the IC industry needs a new paradigm in testing chips for the [getkc id="76" comment="Internet of Things"] (IoT). The message was fairly simple to interpret. Existing automatic test equipment (ATE) is well suited to test today’s digital, analog, and mixed-signal chips, though it may be ill-equipped or too expensive to test IoT-based devices. But wha... » read more

IoT Turns To Dust
By Ernest Worthman - 10 Nov, 2014 - Comments: 0

The current thinking for the [getkc id="76" comment="Internet of Things"] is that a single or bi-directional interface will be attached to just about everything. It will be an amalgamation of hardware and software that will sense whatever we want, assess it anyway we want, and send it anywhere we want—or where someone else wants. "There has probably never been a more exciting time to work ... » read more

Efficient Noise Analysis For Complex Non-Periodic Analog/RF Blocks
By Mentor, a Siemens Business - 25 Jun, 2014 - Comments: 0

Noise minimization is a required design objective for advanced analog and RF circuits. Unlike digital circuits, where noise is a second-order effect, noise in analog and RF circuits directly affects system performance metrics such as signal to noise ratio (SNR) and bit error rate (BER). Effective design optimization in the presence of random device noise is challenging because the noise sources... » read more

Wireless Security Issues Grow
By Ernest Worthman - 01 May, 2014 - Comments: 0

The Internet, as we know it today, is still mostly an information highway. However, even as we speak, more and more once autonomous, physical objects are becoming intelligent. That includes the obvious ones, such as today’s smart communications devices, to the not so evident ones, such as pacemakers, vehicles, audio/video, and environmental sensors. There are microscopic cameras that are swal... » read more

Blog Review: April 30
By Ed Sperling - 30 Apr, 2014 - Comments: 0

Applied Materials’ Jeremy Read points to a looming problem for the Internet of Things—legacy fabs that will require software upgrades and advanced process control. Also needed: Sensors attached to thousands of machines for predictive maintenance. Foundries are now ready for production finFETs. Cadence's Richard Goering captures the buzz at last week’s TSMC Tech Symposium, where the ro... » read more

RF Periodic Stability Analysis
By Various Writers - 09 Apr, 2014 - Comments: 0

The PSTB (periodic stability) analysis feature in Cadence Spectre RF Simulation Option performs stability analysis for circuits with periodically time-varying operating points. PSTB is the periodic equivalent of linear stability (STB) analysis in that it calculates the small-signal loop gain, gain margin, and phase margin around a periodic operating point. PSTB is useful in applications such as... » read more
