Transient IR Voltage Drops in CMOS-Based Power Distribution Networks

Incorporating Voltage Fluctuations of the Power Distribution Network into the Transient Analysis of CMOS Logic Gates

Decreased power supply levels have reduced the tolerance to voltage changes within power distribution networks in CMOS integrated circuits. High on-chip currents, required to charge and discharge large on-chip loads while operating at high frequencies, produce significant transient IR voltage drops within a power distribution network. These transient IR voltage drops can affect the propagation ...

Fast Transient Hybrid Neuro Fuzzy Controller for STATCOM During Unbalanced Voltage Sags

A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid. Unbalanced sags are the most common type of voltage sags in distribution networks. A static synchronous compensator (STATCOM) is generally used to maintain...

Optimized Fuzzy Controller Design in Unbalanced Voltage Drop Mode for Dynamic Voltage Restorer

The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways...

Semi-custom VLSI Design and Realization of DC-DC Converters in UMC90

As CMOS technology is scaling down, the effect of voltage drop in power distribution network is becoming more prominent. Such voltage drops on power lines in a clock network introduces significant amount of skew, thereby degrading the signal integrity. With rising power consumption and decreasing supply voltages, the supply current will increase in future devices. The IR drops can be reduced by...
