چکیده

An active decoupling circuit is proposed to suppress on-chip power supply noise in digital VLSI circuits with focus on circuits using low power methodologies like power gating and Dual Vdd. The circuit is designed using 180nm technology and is tested for an ISCAS benchmark for effectiveness in suppressing noise effects as compared to passive decoupling capacitors and previous works. We show a boost of around 33X in the decoupling capacitance values over conventional passive capacitors. The noise rejection is shown to be around 8dB.

Low Dropout Based Noise Minimization of Active Mode Power Gated Circuit

Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...
