This paper proposes a novel control technique for Switched Capacitor Voltage Regulators (SCVRs) that reduces voltage ripple through capacitance reconfiguration. The proposed approach supports wide load range at high efficiency and power densities, enabling new class of operation in near-threshold applications. An SCVR design is implemented 45 nm CMOS SOI process to demonstrate the different conditions. Simulation results show achieving (74-80%) across 5-125 mA with current density 1.25 A/mm2.

The primary goal of the case is to analyse how Rolls-Royce, a brand traditionally associated with extravagance, used its resources make substantial contribution society during global crisis. research methodology for this study included case-based investigation an engineering business that has pioneered in power generation, aerospace and military. We split into two phases: identifying hurdles L&D practices finding solutions. exploratory relies on secondary data sources such as websites,...

Presents the world's first integrated analog front-end (AFE) and audio codec IC supporting WCDMA standard. This chip was fabricated on Intel's 0.18 /spl mu/m flash+logic+analog (FLA) process technology using a 0.35 feature size transistor. The AFE transmit path contains 10-bit segmented R2R D/A, self-calibrated active RC filter programmable gain amplifier (PGA) with self tuning offset correction circuit. receive includes an 8-bit A/D built-in correction. operates at 2.7 V current consumption...

Design of integrated very low intermediate frequency (VLIF) RF receivers with better than 35 dB image rejection (IR) usually requires detection and calibration l/Q channel mismatches less 0.1 in amplitude 1.8 degree phase. A mismatch amplification technique for improving sensitivity is presented this paper. The proposed transfer function provides an effective method to calculate internal phase from the measured EVM at receiver output. Experimental data VLIF test chip used demonstrate theory....

Near-threshold operation offers energy efficiency at the expense of increased performance variability. Adaptive Voltage/Frequency Scaling (AVS/AFS) techniques can be used to mitigate variability, yet their impact on has not been characterized. This paper defines different system scenarios for near-threshold design and assesses AVS/AFS each case. It is found that AVS are more effective tracking in case low leakage systems, while AFS provide better high Moreover, it operating points chosen...
