A reconfigurable sense amplifier with auto-zero calibration and pre-amplification in 28nm CMOS

This work presents an area-efficient and variation-tolerant small-signal differential sensing (VTS) scheme that modifies the conventional SA circuit to include: 1) a structure for on-the-fly, auto-zeroing offset compensation, 2) pre-amplification of …

Bubble Razor: Eliminating Timing Margins in an ARM Cortex-M3 Processor in 45 nm CMOS Using Architecturally Independent Error Detection and Correction

We propose Bubble Razor, an architecturally independent approach to timing error detection and correction that avoids hold-time issues and enables large timing speculation windows. A local stalling technique that can be automatically inserted into …

Bubble Razor: An architecture-independent approach to timing-error detection and correction

Several methods that eliminate timing margins by detecting and correcting transient delay errors have been proposed. These Razor-style systems replace critical flip-flops with ones that detect late arriving signals, and use architectural replay to …
