Introduction to Fast Locking

This paper presents a fast locking and wide range input frequency all-digital duty cycle corrector (ADDCC).

To maintain a low Kvco and fast locking, the automatic frequency band selection circuit also has two indigenous, most probable voltage levels.

This paper proposes an all-digital duty cycle corrector with synchronous fast locking, and adopts a new quantization method to effectively produce a phase of 180 degrees or half delay of the input clock.

This paper considers design procedure of fast locking time self-tuning [Formula: see text] biquadratic band-pass filter with nonlinear sliding mode control.

A fast locking technique for phase locked loop (PLL) is presented.

A half-rate CDR architecture is presented which exploits an improved half-rate Linear Phase Detector (LPD) and a proposed half-rate Multi-Level Bang Bang PD (MLBBPD) incorporated in a Composite PD (CPD) to benefit the advantages of both the MLBBPD and LPD such as fast locking and good jitter performance, respectively.

To enable high sensitivity and robust-PVT operation, a fast locking phase-locked-loop (PLL) with initial random phase error reduction is proposed to continuously adjust the center frequency deviations of the SR oscillator (SRO) without interrupting the input data stream.

This paper presents a wide tuning, low phase noise, and fast locking CMOS integer-N frequency synthesizer with 1 V power supply.

3 kg, and a fast locking time of 3 s (from the free running state to the repetition-rate-locked state).

13um fast locking and low phase noise PLL are proposed, of which the phase-locking speed of the PLL is improved by the current steering charge pump, and the output differential buffer unit is used to stabilize the VCO output waveform for reducing the phase noise.

The proposed dual-mode time division multiplexing DAPD has coarse-resolution and fine-resolution modes, which is used in fast locking and CP calibration, respectively.

To support fast locking (during frequency scaling), we present novel architecture with a socalled “fast-locking mode” - in which the control code for the Long-Range Delay Block (LRDB) can be quickly determined in a way that the overall delay across the underlying DLL can be roughly one or multiple clock cycle times of the input clock signal.

To break current device limitations, quantum materials including nanocrystal semiconductors and 2D semiconductors, may lead to novel device physics due to their unique ultrafast photophysics phenomena such as phonon bottleneck effect, multiple exciton interaction, and phase transition ultrafast locking.

This work presents 32-phase analog delay-locked-loop (DLL) having fast locking ability, startup-circuit free operation, and a low area with improved DNL-INL performance.
