On-Die Supply-Voltage Noise Sensor with Real-Time Sampling Mode for Low-Power Processor Applications

Managing Temperature Effects in Nanoscale Adaptive Systems

“…Unfortunately, supply voltage can spike and droop on a sub-nanosecond timescale [139], meaning that little can be done to adapt to the fastest harmonics aside from reducing the magnitude of these variations. The separation of voltage and temperature variation can be implemented using voltage [140] and temperature sensor readings.…”

“…While temperature generally varies on a very slow timeframe, low-power idle modes may also run at very slow frequencies, making temperature variation guardbands more important. To prevent errors due to voltage fluctuations, voltage minima over a given time window should be recorded using a real-time sampling method [140].…”

Introduction to Noise-Resilient Computing

“…Intensive study has been made on noise in the logic circuits using a special technique recently developed [116,118]. When the FET switches on, current flows from the voltage source to the ground.This event takes place at certain clock intervals in the circuit.…”
