In this paper, we analyze a noise-to-jitter transfer function on DLL (Delay Locked Loop) considering power supply noise effects on PDN (Power Distribution Network). Noise-tojitter transfer function of DLL circuit can be estimated by using single-tone power supply noise analysis. Noise transfer function through the PDN can be obtained from transfer impedance of hierarchical PDN using TLM (Transm...

This paper deals with the study of the impact of power supply noise on the performance of CMOS Clock and Data Recovery (CDR) Circuits. The sensitivity of the various blocks of the dual loop CDR circuit to power supply noise is first studied and then it is demonstrated that insertion of suitable Low Dropout Regulators (LDOs) can enhance the performance of the CDR system with respect to power sup...

High-power high-voltage dc power supply has been developed based on series resonant converter technology for a MW class RF amplifier. For low-voltage ripple, an IGBT inverter consisting of 1400 V-600 A devices is drives with a maximum switching frequency of 31.2 kHz. A performance test was carried out using an RF amplifier. We examined this power supply under two different conditions. One was w...

Its output ranging from 0 to 50 volts and 0 to 10 amperes, this 200W, series-re gulated, laboratory power supply spans a range that would normally require three power supp/ies, and it can be programmed by way of the HP interface bus. f AB SECTION MANAGERS, production en-I-r gineers, and materials engineers often face a difficult choice when specifying the purchase of a power supply for their op...

The energy efficiency of battery-operated portable applications can be improved by increasing the efficiency of power amplifiers (PAs). By dynamically changing the supply voltage from the fixed battery supply using a DC-DC converter, the PA can be operated with high efficiency during power back-off. This paper presents the system level requirements for a buck converter and other blocks in a dyn...

A power efficient gain adjustment technique is described to realize programmable gain current mirror. The dissipation power changes over the wide gain range of structure are almost negligible. This property is in fact very interesting from power management perspective, especially in analog designs. The simple structure and constant frequency bandwidth are other ever-interesting merits of propos...

This paper proposes a high frequency ring oscillator with low power consumption. The proposed ring oscillator is based on Gated Ring Oscillator (GRO) by applying boot strap technique. Simulation results indicate that the FoM (Power Consumption /Oscillation Frequency) of the proposed ring oscillator is greater than that of the conventional ring oscillator. Figure 1 shows delay element using boot...
