A sense amplifier is a circuit that is used to amplify and detect small signals in electronic systems. It is commonly used in memory circuits, such as dynamic random access memory (DRAM) , to read and amplify the weak signals stored in memory cells.
Current sense amplifiers (also called current shunt amplifiers) are special-purpose amplifiers that output a voltage proportional to the current flowing in a power rail. They utilize a "current-sense resistor" to convert the load current in the power rail to a small voltage, which is then amplified by the current-sense amplifiers.
In electronics, sense is a technique used in power supplies to produce the correct voltage for a load. Although simple batteries naturally maintain a steady voltage (except in cases of large internal impedance ), a power supply must use a feedback system to make adjustments based on the difference between its intended output and its actual output.
Operational amplifiers (op-amps) are commonly employed to carry out the amplification of the signal in the signal conditioning stage. In some transducers , signal conditioning is integrated with the sensor, for example in Hall effect sensors .
This relationship can be used to sense currents. Sensors based on this simple relationship are well known for their lower costs, and reliability due to this simple principle. Shunt resistor. The common and simple approach to current sensing is the use of a shunt resistor.

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude (magnitude of the voltage or current) of a signal applied to its input ...
