Abstract:
A circuit comprising:a sense amplifier having (1) an input matched differential p-channel field effect transistor (FET) pair source coupled between a power supply node and a power return node, each FET of the input pair having gate, drain, source, and bulk regions, (2) first and second output nodes whose voltages are to be driven in opposite directions by the input pair, each output node to provide a full voltage swing between the supply and return nodes, (3) a reset circuit coupled to selectively equalize the first and second output nodes, and (4) a p-channel switching field effect transistor coupled in series between a common source of the pair and the power supply node; one of a digital logic gate and a latch, having an input coupled to receive the full swing and in response provide at an output one of only two stable DC voltages; and forward body bias (FBB) generation circuit coupled to the bulk region of each FET of the input pair and of the switching FET in the sense amplifier.
