Researchers at the University of California, Davis have developed a new class of lasers and amplifiers that uses a CMOS-compatible electronics platform - and can also be applied to nano-amplifiers and nano-lasers applications.

Phase locked loops are widely employed in radio, telecommunications, computers and other electronic applications. They can be used to demodulate a signal, recover a signal from a noisy communication channel, generate a stable frequency at multiples of an input frequency, or distribute precisely timed clock pulses in digital logic circuits such as microprocessors. Researchers at the University of California, Davis have invented a novel, sub-sampling phase-locked, loop (SSPLL) that uses a sub-sampling lock detector (SSLD) to monitor the harmonic selected by the SSPLL. This technology requires lower energy consumption and reduces signal noise.

Researchers at the University of California, Davis have developed a phase noise filter (PNF) circuit with wide bandwidth and high sensitivity.

Researchers at the University of California, Davis have developed a hybrid, complementary metal-oxide semiconductor (CMOS) mm-wave, single-polar single-throw (SPST) switch that combines the wide bandwidth features of a distributed structure and the compact implementation of coupled lump elements for an area-efficient layout.

This invention utilizes standard printed circuit board (PCB) fabrication technology to create a novel high-quality factor (Qu) continuously-tunable resonator and filter. The inherent benefits of the proposed design are: 1) flexibility in choosing various types of tuning components (e.g. solid-state, ferroelectric, and radio frequency microelectromechanical systems (RF MEMS) varactors), 2) compared to traditional cavity tunable resonators, the initial starting frequency is primarily determined by the tuning element as opposed to precise assembly techniques, and 3) industry-standard PCB substrates with commercially-available tuning components are used, thereby facilitating high-volume manufacturing, ease of integration with other RF front-end components and lower fabrication costs. A tunable resonator and two-pole bandpass filter with solid-state varactors are designed and fabricated to experimentally validate the approach. The resonator surpasses the state-of-the-art with a frequency tuning range of 0.5–1.2 GHz (tuning ratio of 2.4 : 1) and a Qu of 82–197. The bandpass filter exhibits frequency tuning of 0.57-1.17 GHz, insertion loss of 4.9-1.9 dB and a 3-dB bandwidth of 2-8 %. Lastly, an RF MEMS varactor enabled tunable resonator based on the same design further shows Quof 240 at 6.6 GHz.
