Well it comes as no surprise to those that use and design them, that PLL’s are a world unto themselves and very complicated indeed. With PLL’s we are talking about analog designs that rely on ring oscillators or LC tanks. They are needed on legacy nodes, like the ones that IoT chips are based on, and they are crucial for high speed advanced… Read More

Tuning Analog IP for High Yield at SMIC
Analog IP is more difficult to design and optimize for a given process node compared to digital IP, so any automation for analog designers is always welcome. The engineers at SMIC in China have customers that design analog IP and often they need to know how to optimize it for a specific process, so I watched a presentation by Josh Yang,… Read More
Managing Design Flows in RF Modules
The semiconductor industry is expected to grow at a reasonable pace in 2015 and beyond, with the biggest market being compute applications followed by wireless and consumer applications. The highest growth, however, is expected to be in application-specific products for devices such as smartphones, wearables, memories, … Read More
Simple Analog ASIC Solves Thermal Analysis Problems
In a world where Application Specific Integrated Circuits (ASICs) and Application Specific Standard Products (ASSPs) are dominating every conceivable application, greater attention is being applied to their long term reliability. These chips are being built on smaller lithographies, running at higher speeds, dissipating… Read More
How to detect weak nodes in a power-off analog circuit?
Most analog cells have a power off mode intended to reduce power consumption. In this mode, all the circuit branches between the supply lines are set in a high impedance mode by driving MOS gates to a blocking voltage. This is a somewhat similar situation to that in tri-state digital circuits.
When a branch is set in that high impedance… Read More
Digital, Analog, Software, IP – Isn’t it all just the same?
Designing an SoC requires a team, and the engineers typically use lots of specialized EDA software and semiconductor IP to get the job done. Many have started to ask about how designing a chip is different than designing and managing a large software project, or how is analog design different than digital design in terms of managing… Read More
Want to learn Mixed-Signal Design and Verification?
Workshops are a great where to learn hands-on about IC design technology. Mentor has a free workshop to introduce you to creating, simulating and verifying mixed-signal (Analog and Digital) designs.
