Founded: 2002
Founders: Michael McCorquodale (MSE PhD EE '00 '04), Prof. Richard Brown
Product/Service: Semiconductor technology focused on mixed-signal integration
Acquired By: Acquired by IDT Jan 14, 2010

Based in Silicon Valley, Mobius Microsystems is a fabless semiconductor company, and the first to implement accurate frequency generators on a single, standard CMOS die. This is a significant technical breakthrough in frequency generation, which up to now had been accomplished with quartz-based crystals, crystal oscillators and PLL ICs. Mobius' patented CMOS Harmonic Oscillator (CHO™) eliminates such components, and enables designers to create robust products offering higher frequency and thinner profiles. Mobius' proprietary technology builds on work done at the University of Michigan by Michael cCorquodale, Ph.D., CTO of the company. Mobius is funded by leading venture capital firms, has an extensive patent portfolio, and has been recognized as a company to watch by its industry peers. "The industry has long recognized the value of building frequency references monolithically in CMOS, but many thought it simply could not be done, and that quartz crystals would always be needed. obius proves the contrary; it can be done with CMOS. Our technology enables smaller, thinner, and more mechanically robust products for a wide array of applications." - Ashok Dhawan Chief Executive Officer, Mobius Microsystems.

Integrated Device Technology: Crystal-free oscillators finally enable quartz device replacement



As semiconductor technology continues to advance, the limitations of quartz technology do not scale well in price, size, frequency, capacity, and lead-time like silicon-based technology does. Leveraging semiconductor economies of scale to enable high performance, low price, and short lead time, the 3LG family of CrystalFree CMOS oscillators feature a breakthrough 50-ppm frequency accuracy while replacing traditional quartz crystal-based oscillators for up to 75% power savings in a broad range of applications, including computing, communications, and consumers products.

They generate stable frequencies up to 125 MHz and offer high-performance phase jitter of less than 1 ps over the wide frequency offset of 12 kHz to 20 MHz. In addition, they are the only technology and product capable of replacing active XOs and passive XTALs as both packaged devices and die.

Michael McCorquodale first UI Engineer in Residence

URBANA The Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign announces its first Engineer in Residence. Dr. Michael S. McCorquodale, a 1997 electrical engineering graduate of the University of Illinois, will be part of a special program in ECE on March 9 and 10.

McCorquodale founded Mobius Microsystems in 2004, based on research he did during his graduate studies at the University of Michigan. Mobius was the first company to develop high-accuracy all-silicon complementary metal-oxide-semiconductor (CMOS) oscillator products capable of replacing quartz crystal resonators and oscillators, which constitute a market exceeding $5 billion.

McCorquodale will speak about his experiences with Mobius at 5 p.m. on Wednesday in 151 Everitt Lab. He will be available in 159 Everitt from 9 a.m. to noon the following morning for walk-in visits with students.

CMOS oscillator said to beat quartz

PORTLAND, Ore. — Integrated Device Technology Inc. has introduced what it claims is the world's most accurate all-silicon CMOS oscillator with the industry's highest frequency accuracy, measured in parts per million (ppm).

Synchronizing high-speed digital circuitry needs rock-solid time bases, which usually means quartz-crystal based oscillators. CMOS oscillator makers, however, claim to be pioneering a new breed of digital time bases that are faster than quartz crystals yet smaller and lower power than MEMS.

100ppm CMOS oscillators challenge crystals

IDT is sampling an all-silicon CMOS oscillator, achieving 100ppm total frequency error across temperature, voltage and other factors.

The technology as acquired by IDT when it bought Mobius in January. The founding CEO of Mobius, Michael McCorquodale, now general manager of IDT's silicon frequency control business, said the technology has taken 12 years to develop.

Timing Is Everything

IEEE Senior Member Michael McCorquodale has managed a feat that vexed engineers for decades: He has built a stable silicon timing device that does not rely on quartz crystals. Now his invention is poised to challenge quartz timing as the status quo.

Timing devices—also known as oscillators, frequency references, and clock generators—enable electronics to “talk” to one another. They’re inside most digital devices and generate constant, repetitive frequencies by which data can be exchanged via circuit paths, USB, wireless, and other interfaces. For example, the iPhone uses seven quartz frequency references.
