The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...

Few topics in electrical engineering have demanded as much attention over the years as the phase-locked loop (PLL). The PLL is arguably one of the most important building blocks necessary for modern ...

One of the most challenging tasks in analog circuit design is to adapt a functional block to ever new CMOS process technology. For digital circuits the number of gates per square mm approx. doubles ...

A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes the ...

San Francisco, CA. At the 2017 International Solid-State Circuits Conference in San Francisco, imec, Holst Centre, and ROHM presented an all-digital phase-locked loop (ADPLL) for Internet-of-Things ...

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...

A novel fast locking Digital Phase-Locked Loop (DPLL) has been proposed with simple control unit to improve locking time. A Frequency Difference Stage (FDS) is added to produce a 3-bit code represents ...

Scientists have developed an advanced phase-locked loop (PLL) frequency synthesizer that can drastically cut power consumption. This digital PLL could be an attractive building block for Bluetooth Low ...

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Socionext Inc. have designed the world's smallest all-digital phase-locked loop (PLL). PLLs are critical clocking circuits in virtually all ...

A resolver is a sensor that estimates the angle of a rotating shaft, such as the shaft of an electrical motor used in automotive traction inverter applications. To obtain a digital representation of ...

The Intuitive Internet of Things, or I2oT, is a concept imec has been working to bring to fruition. Speaking at the imec Technical forum held in conjunction with SEMICON West 2015, Luc Van den hove, ...
