    en.wikipedia.org/wiki/Sense_amplifier

    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.

  3. Current sense amplifier - Wikipedia

    en.wikipedia.org/wiki/Current_sense_amplifier

    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 amplifi

  4. Sense (electronics) - Wikipedia

    en.wikipedia.org/wiki/Sense_(electronics)

    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.

    A sense amplifier is essentially a pair of cross-connected inverters between the bit-lines. The first inverter is connected with input from the + bit-line and output to the − bit-line. The second inverter's input is from the − bit-line with output to the + bit-line.

  6. Sense switch - Wikipedia

    en.wikipedia.org/wiki/Sense_switch

    Sense switches and output lights, upper right. on an IBM 701, introduced in 1952 Sense switches on a Data General Eclipse S/130, lower left. A sense switch, or program switch, is a switch on the front panel of a computer whose state can be tested by conditional branch instructions in software. [1] Most early computers had several sense switches.

    They are activated by an external magnetic field. In this generalized device, the Hall sensor senses the magnetic field produced by the magnetic system. This system responds to the quantity to be sensed (current, temperature, position, velocity, etc.) through the input interface. The Hall element is the basic magnetic field sensor.

  8. Push–pull output - Wikipedia

    en.wikipedia.org/wiki/Push–pull_output

    A push–pull amplifier produces less distortion than a single-ended one. This allows a class-A or AB push–pull amplifier to have less distortion for the same power as the same devices used in single-ended configuration. Distortion can occur at the moment the outputs switch: the "hand-off" is not perfect. This is called crossover distortion.

  9. Power semiconductor device - Wikipedia

    en.wikipedia.org/wiki/Power_semiconductor_device

    Amplifiers operate in the active region, where both device current and voltage are non-zero. Consequently power is continually dissipated and its design is dominated by the need to remove excess heat from the semiconductor device. Power amplifier devices can often be recognized by the heat sink used to mount the devices. Multiple types of power ...
