A 285-fsrmsIntegrated Jitter Injection-Locked Ring PLL with Charge-Stored Complementary Switch Injection Technique

Orbit – a Ring Injection Code with Space Charge

ORBIT, Objective Ring Beam Injection and Tracking, is a new C++ code developed for the Spallation Neutron Source (SNS) project to build the most intense pulsed neutron source. The code includes H foil injection modelling features needed to simulate realistic injection scenarios. Because the SNS project will produce intense pulses, 1-2x10, of low energy protons, 1 GeV, and is concerned with keep...

A Direct Injection-Locked QPSK Modulator Based on Ring VCO

QPSK or Quadrature Phase-Shift Keying is a higher order modulation scheme used in digital modulation. A direct injection locked QPSK modulator uses VCO for minimize the area of the conventional modulator. In this project injection locking scheme is used since injection locking has an advantage inphase-noise reduction ofoscillators withavery simplecircuittopology. By using proposed simple modula...

A 0.048mm 3mW Synthesizable Fractional-N PLL with a Soft Injection-Locking Technique

Phase-locked loops (PLLs) are a crucial building block in modern Systems-onChip (SoCs), which contain microprocessors, I/O interfaces, memories, power management, and communication systems. Fully synthesizable PLLs [1-2], designed using a pure digital design flow, have been proposed to reduce the design cost and allow easier integration. To achieve high-frequency resolution, PLLs are required t...

Superharmonic Injection-Locked Frequency Dividers

Injection-locked oscillators (ILO’s) are investigated in a new theoretical approach. A first-order differential equation is derived for the noise dynamics of ILO’s. A single-ended injection-locked frequency divider (SILFD) is designed in a 0.5m CMOS technology operating at 1.8 GHz with more than 190 MHz locking range while consuming 3 mW of power. A differential injection-locked frequency divid...
