Using the obtained expressions it is possible to establish a connection between the rise time t rise and the product 伪W eff of the absorption coefficient 伪(位) and effective depletion layer width W eff( W) at various ratios of the diode thickness and the effective depletion layer width. ...
Explicit delay and rise time formulas are computed from the transfer function using Elmore's definitions. Examples are included to illustrate the use of the formulations given for delay and rise times. As a special case, the proposed expressions are verified with the SPICE 5 circuit analysis ...
Let’s take a look at slew rate, a concept similar to rise time but with some important differences. As shown inFigure 1, the rise time of a step response is defined as the time it takes for the waveform to transition from 10% to 90% of the final value. (Sometimes rise time is ...
Figure 5: The RC low-pass filter circuit is often used as a simple model of low-pass filter behavior. It can be used to derive a relationship between rise time and 3 dB bandwidth. The RC low-pass filter circuit, shown in Figure 5, is often used to model low-pass filter behavior. ...

Assuming an input voltage of a unit step function, one can easily determine the speed of response by solving for t. Solving for t, and replacing RC with the circuit time constant (τ) we get: (4) (5) (6) (7) With Equation (7) at our disposal, we can now calculate the transitory...
Rise/fall time of the clock waveform is only one of the factors that contributes to clock jitter...

18. A circuit for fast switching of current to a light emitting diode (LED) comprising: one or more LEDs; a voltage source; a first switching metal oxide semiconductor field-effect transistor (MOSFET) having a drain, gate, and source, the drain of the first MOSFET coupled to the inductor...
During a low-to-high signal rising edge, the rise time accelerator (RTA) circuit turns on to increase the current drive capability of the driver. This edge-rate acceleration provides high ac drive by bypassing the internal 10-kΩ pull up resistors during the low-to-high transition to speed...
