Sense amp offset methodology

Webvery suitable sense-amplifier for offset-critical applications. This paper discusses the double-tail sense amplifier in more detail. The next section starts with a short discussion of the conventional sense amplifier and its drawbacks. Section three subsequently discusses the operation of the double-tail sense amplifier and what its advantages are. WebThe key idea is to improve bit error rate (BER) with an energy-efficient offset prediction-based sense amplifier (OPB-SA) for static random access memory (SRAM). The OPB-SA effectively compensates for the branch current mismatch due to threshold voltage (VTH) offset in SA sensing devices.
