New Frequency-Locked Loop Based on CMOS Frequency-to-Voltage Converter: Design and Implementation

In this paper, we describe the architecture of a new CMOS fully integrated frequency-locked loop (FLL). The proposed FLL contains a frequency-to-voltage converter (FVC), an operational amplifier (opamp) and a differential voltage-controlled oscillator (VCO). The operation of the proposed circuit is based on frequency comparison of a reference and feedback signals. The architecture of the FVC is...

the comparative impact of prompts and recasts in processing instruction versus meaningful output-based instruction on efl learners’ writing accuracy

the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...

Frequency Synthesizer Based on Flying Adder Architecture and Phase Locked Loop

Frequency synthesis is one of the most important and most actively researched subjects in the field of VLSI mixed-signal circuit design. Among the existing techniques in this area, phase locked loop fractional architecture is a widely used one for generating frequencies which are not integer multiple of the input reference frequency. Flying-Adder architecture is an emerging technique which is b...

Towards chip-scale optical frequency synthesis based on optical heterodyne phase-locked loop.

An integrated heterodyne optical phase-locked loop was designed and demonstrated with an indium phosphide based photonic integrated circuit and commercial off-the-shelf electronic components. As an input reference, a stable microresonator-based optical frequency comb with a 50-dB span of 25 nm (~3 THz) around 1550 nm, having a spacing of ~26 GHz, was used. A widely-tunable on-chip sampled-grati...
