In electronics and electromagnetics, slew rate is defined as the change of voltage or current, or any other electrical or electromagnetic quantity, per unit of time. Expressed in SI units , the unit of measurement is given as the change per second, but in the context of electronic circuits a slew rate is usually expressed in terms of ...

Slew rate is the maximum rate of change of the output, usually quoted in volts per second (or microsecond). Many amplifiers are ultimately slew rate limited (typically by the impedance of a drive current having to overcome capacitive effects at some point in the circuit), which sometimes limits the full power bandwidth to frequencies well below ...
When slew rate limiting occurs, further increases in the input signal have no effect on the rate of change of the output. Slew rate limiting is usually caused by the input stage saturating; the result is a constant current i driving a capacitance C in the amplifier (especially those capacitances used to implement its frequency compensation ...
This circuit can be viewed as an active low-pass electronic filter with a single pole at DC (i.e., where =). Its practicality is limited by a significant problem: unless the capacitor is periodically discharged, the output voltage will eventually drift outside of the operational amplifier's operating range.
In electronics engineering, frequency compensation is a technique used in amplifiers, and especially in amplifiers employing negative feedback.It usually has two primary goals: To avoid the unintentional creation of positive feedback, which will cause the amplifier to oscillate, and to control overshoot and ringing in the amplifier's step response.
In electronics, a comparator is a ... Almost all op-amps have an internal compensation capacitor which imposes slew rate limitations for high frequency signals ...
