SupportDescription
The design of a new bit-line sensing scheme of SRAM memories is presented, which combines offset cancellation and compensation solutions. FCMOS inverters, brought to operate in their maximum gain region, are used to compensate the systematic offset of the sense amplifier and reduce the sensing delay. Systematic offset of the inverter amplifiers is cancelled by means of equalising feedback connections.
