Voltage Sense Amplifiers

  • Bernhard Wicht
Part of the Springer Series in Advanced Microelectronics book series (MICROELECTR., volume 12)


Voltage sense amplifiers evaluate a small voltage difference which is applied at their inputs and convert it into a logic level output signal. According to Fig. 2.4 they can be implemented in voltage sensed SRAM but also in current sensed SRAMs as a second stage. In SRAM all these circuits are basically analog comparators. A wide range of circuits are used. In general they can be classified into static and dynamic circuits. Sect. 3.1 gives an overview while in Sect. 3.2 a circuit is investigated in detail that makes an excellent second stage in a current sense amplifier.
