It’s a Femtosecond World

I fondly recall working on the first generation of 10Gigabit FPGA SERDES and struggling to accurately capture 10 picoseconds of timing jitter on high speed repetitive sampling oscilloscopes. At that time, advanced microwave transition analyzers could discern timing noise below the 1 picosecond level but that was rarely necessary. Since SERDES on those first FPGAs with high speed serial transceivers displayed a fair amount of inherent noise, clock jitter below 1psec rms was generally irrelevant.

Top 5 Adaptations in Timing and Synchronization Enabling the IoT | Abracon LLC

Cutting edge, innovative, and exhilarating, the IoT has caught the attention of millions of businesses and consumers around the world. It’s easy to mistake the technologies of the IoT and their profitability as an overnight success; however, it would not be possible without key innovations over decades of work. At the heart of IoT technology is electronic timing.

Why is Abracon The Heartbeat of the IoT™?

It was the summer of 2012 when a frantic scramble occurred deep within a lab in Silicon Valley. At a time when wearables and other IoT markets were just starting to ramp, a show stopping problem was discovered. With wearables shipments in the low millions for the first time, this problem had to be solved. Panicked, highly skilled engineers on multiple coasts and across continents attempted to solve the problem. The quartz crystal on the MCU would not reliably start.

Over Temperature Effects of Gm_critical | A Technical Review

The emergence of the IoT has accelerated the trend towards lower power consumption on many MCU and RF chipsets, pressuring IC designers to wring out every bit of energy savings in their circuits. The consequence, pertaining to the clocking scheme, is usually a weaker oscillator loop amplifier starved of transconductance (gm). The reduced power consumption has the potential to severely affect analog circuits, such as the Pierce oscillator.

How Critical is Gm_critical?

The trend toward increasingly low power consumption for many MCU and RF chipsets has accelerated with the emergence of the Internet of Things (IoT). This trend pressures IC designers to wring out every bit of energy consumption in circuit design. Oscillator design geared toward low power consumption comes with an inherent side effect; the loop is starved of gain also known as the transconductance (gm). Although not of great disadvantage in the digital design domain, analog circuits can be severely affected by reduced power consumption, particularly the Pierce oscillator.
