How to increase slew rate
Web1 Answer Sorted by: 0 Turn-off slew rate depends on load current only as each switch opens. Turn-On slew rate is fastest due to T=RC when the switch is on at R=RdsOn. The same is true for collector slew rates in a BJT transitor. Turn off time depends on the pullup-R * C =T where C can be stray capacitance to ground. The 1st principal is Web21 sep. 2024 · Contrary to popular belief, the slew rate of the op amp has little bearing on its performance due to the small signal nature of these measurements. Instead, the operational amplifier (op amp)’s gain bandwidth (GBW) ... and close-loop gain, G CL, of the application and not its slew rate. This results in a rise time, t R, of 350 µs ...

Webrate-of-change is: p max 2 fV dt dv = π. Eq. 2 . To reproduce this signal without distortion, an amplifier must be able to respond in terms of its output voltage at this rate (or faster). When an amplifier reaches its maximum output rate-of-change, or slew rate, it is said to be slew limiting (sometimes also called rate limiting). So, we Web26 dec. 2016 · With the slew rate being dV/dt=Ic/C for the cap and Ic = (V+-Vcap)/ (RdsOn+ESR (diode)) it becomes highly nonlinear. But with initial conditions of ESR diode=10, and ESR or RdsOn of FET=10Ω then dropping to 0.34 Ω as Vds drops below 3V. Ic=C dV/dt=1e-9 * (5V)/ (10Ω+10Ω) and C= 1e-9F for Vds=3~5V slew rate dV/dt= Ic/C= …
