Advanced High-Frequency Electronic Ballasting Techniques for Gas Discharge Lamps
… of high-frequency electronic ballasts for gas discharge lamps. However, power line quality and electromagnetic interference (EMI) issues arise when a simple peak rectifying circuit is used. To suppress harmonic currents and improve power factor, input-current-shaping (ICS) or …

Design and Implementation of Low Jitter Clock Generators in Communication and Aerospace System
… closed loop VCO and an overdamping system with a charge pump (CP) current proportional to the VCO frequency for the adaptive-bandwidth technique. The proposed adaptive-bandwidth PLL presents 0.6% RMS jitter over the entire frequency range from 320 MHz to 2.56 GHz, which is 70% smaller than the …

Low jitter phase-locked loop clock synthesis with wide locking range
… new circuit architectures are employed for the charge pump circuit and phase-frequency detector (PFD) to minimize the timing jitter due to the finite dead zone in the PFD and the current mismatch in the charge pump circuit. The selection of the optimum PLL loop bandwidth is critical in …
